A mole is how chemists define an amount of substance, useful when dealing with many different molecules reacting at once i. The official International System of Units definition is that a mole is the amount of a chemical substance that contains exactly 6. Prior to that, a mole was defined as the number of atoms in 12 grams of carbon an isotope of carbon.

Turns out that memorising that definition for my GCSE chemistry exam was pointless. So why do chemists use moles, and why do you need a mole calculator? Well, as we said above, it provides a useful metric when dealing with reactions. Maybe an example would explain it best.

Lets say you want to neutralise 10 g of hydrochloric acid HCl in water with some sodium hydroxide NaOH. Now, you want the resulting solution to be perfectly neutral, so you don't want to add too much or to little NaOH, making it too basic or acidic respectively. It is therefore useful to find out exactly how many molecules of HCl are in the solution. This is where moles come in handy.

To know how to calculate moles, the equation is:.

Calculating Moles using Avogadro's Number

If you wanted to find the concentration of the hydrochloric acid, you could use our concentration calculator. Let's do a quick example to help explain how to convert from moles to grams, or grams to moles. We know we have 10 g of HCl, and it has a molecular weight of Lets plug these numbers into the above equation:.

We can work out the number of molecules by timesing the moles by Avogadro's constant above.This calculator can solve problems on the molarity or molar concentration of a solute in a solution. First, it can calculate the molar concentration of a solute given a solute chemical formula, mass of the solute and volume of the solution.

Second, it can calculate the mass of a solute given a solute chemical formula, volume of the solution and desired molar concentration of a solute. It you want to recall the topic, you can find some definitions and formulas below the calculator.

Let's recall some definitions: A solution is a mixture where the ratio of solute to solvent remains the same throughout the solution homogeneous mixture or mixture with uniform composition.

Solvent is the chemical that is present in larger amount, and solute is the chemical that is present in smaller amount. The problems on molarity usually involve calculation of either molar concentration of a solute, given the mass of a solute and the volume of a solution or mass of a solute for the desired molar concentration given the volume of a solution. In both cases, the tedious part is the convertion of the mass of a solute to moles of the solute or vice versa, because it involves the calculation of molar mass of a solute.

Happily, we can reuse the Molar mass of the substance calculator for this.

The majority of these materials are not pure. They are, in fact, mixtures. Mixtures consist of a collection of different compounds. Sometimes the number of elements may be quite high, or sometimes quite low, but as long as there is more than 1 element in an object, it is a mixture.

Orange juice in your glass, a cup of tea, detergents in the bathroom or milk - all these substances are mixtures. Mixtures are not limited to just liquids though, solids and gases can both be mixtures; even biological organisms are very complex mixtures of molecules, gases, and ions dissolved in water. Homogeneous mixtures - components are uniformly distributed throughout the mixture, and there is only one phase of matter observed.

They are also known as solutions and may occur in the solid, liquid or gaseous state. It is not possible to simply separate the mixture components, but no chemical change has occurred to any of the components. Examples: sugar water, dishwashing detergent, steel, windscreen washer fluid, air.

Heterogeneous mixtures - components of the mixture are not uniformly distributed and may have regions with different properties. Different samples of the mixture are not identical. At least two phases are always present in the mixture, and it's usually possible to physically separate them.

A few examples of such substances: blood, concrete, ice cubes in cola, pizzathe Pacific Ocean. Concentration is one of the most well known and most important parameters for anybody who works with any chemical substances or reactions. It measures how much of a substance is dissolved in a given volume of solution.

Chemists use many different units for describing concentration. However, the term molarityalso known as molar concentrationis the most common way of expressing the concentration. When the reactants compounds are expressed in mole units, it allows them to be written with integers in chemical reactions.

This helps to easily work with their amounts. First, let's take a closer look at what is the moleso we can move on later to find what is molarity. The mole is the SI unit of measurement for the amount of substance.

The current definition was adopted in and is based on carbon It says:. When the mole is used, the elementary entities must be specified and may be atoms, molecules, ions, electrons, other particles, or specified groups of such particles.

The word "substance" in the definition should specify be replaced with the name of the substance concerned in a particular application, e. It is crucial to always give a precise specification of the entity involved as noted in the second part of the mole definition. This should be done by providing the empirical chemical formula of the compound involved. According to the newest conventions effective as of the 20 th Maythe mole definition is that a mole is the amount of a chemical substance that contains exactly 6.

That number is known as Avogadro's constant. It's symbol is NA or L. Using the Avogadro number provides a convenient way of considering the weight of substance and the theoretical yield of chemical reactions. Moles allow you to directly read weight from the periodic table e.Molecules are converted to moles and vice versa using the Avagadro's number. The Avogadro's number is a dimensionless quantity and is equivalent to the Avogadro constant, which is 6.

Here is a simple online molecules to moles calculator to convert molecules into moles. Molecules are converted into moles by just dividing the molecules by the Avogadro's number, also known as the Avogadro's Constant.

Avogadro constant is the number of atoms or molecules, that are contained in one mole of any substance, which is equal to 6. Avogadro Constant was named after the scientist Amedeo Avogadro. Molecules to moles conversion is done by either multiplying by or dividing by Avogadro's number. To go from moles to molecules, multiply the number of moles by 6.

We will get through this together. Molarity describes the relationship between moles of a solute and the volume of a solution. Plugging these variables into the basic formula for calculating molarity will give you the correct answer. To calculate molarity, divide the number of moles of solute by the volume of the solution in liters. If you don't know the number of moles of solute but you know the mass, start by finding the molar mass of the solute, which is equal to all of the molar masses of each element in the solution added together.

Once you have the molar mass, multiply the number of grams of solute by 1 over the molar mass to convert the grams into moles. Finally, divide the number of moles by the volume of the solution to get the molarity. To learn how to calculate molarity using moles and milliliters, scroll down! Did this summary help you?

Additional Practice Problem.Mole Fraction Calculator is a smart tool that has been designed to accommodate you in dealing with chemistry equations.

Before going ahead to know about this calculator, let us provide you with the definition of "Mole" followed by the description of "Mole Fraction". Being concerned with Chemistry, you must be aware of the terminology of Moles.

If not, then we are here to let you know about it. In chemistry, Mole can be referred to as the measuring unit used to measure the quantities of atoms, molecules, or compounds present in a solution or mixture. The quantity of a mole is equal to 6. In other words, a mole is a standard international unit used to measure the amounts of the atoms or molecules of the elements or substances that react to form new substances as a result of a chemical reaction.

Precisely, we can refer to a mole as the amount of the fundamental units atoms, molecules, etc. You can calculate the number of moles using the formula:. Before jumping onto the definition of Mole Fraction, you must be aware of the phenomenon to which it is concerned.

What we are calling here a phenomenon is "Chemical Reaction". You must have knowledge about the chemical reactions: what are Reactants, and how these react to form products. A chemical reaction involves the transformation of two or more substances from one form to another as tends to combine with each other.

The substances that are to be transformed and combine with each other are what we call Reactants. On the other hand, the new substance that is formed as a result of the reaction or the combination of the reactants is known as Product s. In the case of a solution or mixture, we can refer the reactants as solute and solvent that combine to form a solution or mixture.

Now, let us throw light on the smallest units of the reactants or the products which in turn is concerned with the mole fraction. The smallest units of the reactants or products can be referred to as the atoms or molecules that are the composite of the respective substance.

These smallest units are weighed as moles as we have already discussed in the upper section. Whereas the ratio of reactant substances solute, and solvent is what we call " Mole Fraction ".

Mole is the number of fundamental units of reactant substances involved in a chemical reaction whereas the fraction is referred to as the division of proportion of the reactant substances, respectively.

As Mole Fraction is the ratio of the reactants, having the values of the moles of the reactants known, you can evaluate the concentration of each reactant involved in a chemical reaction. In turn, having the value of the concentration of the substances known can help you in analyzing and balancing the chemical reactions properly.

By dividing the moles of each reactant with the moles of all reactants, you can calculate the Molar Fraction of respective reactants. Simply, you can calculate the mole fraction by just diving the moles of each reactant with the total number of moles of the whole number of reactants that combine to form the product, solution or mixture. In other words, the division of the number of moles of the solute with the number of moles of both solute and solvent is equal to the mole fraction of the respective solute in a chemical reaction or solution.

For example, if you have 1. So, 0.
