What is Mole?

A mole is the measuring unit which measures the present quanitities of atoms, molecules or compounds in a mixture or solution. The quantity of a mole is equal to 6.02214076×1023

Precisely, we can refer to a mole as the amount of the fundamental units (atoms, molecules, etc.) of a substance that reacts with another element/substance to form a new substance. You can calculate the number of moles using the formula:

$$mole = \frac{mass}{molecular weight}$$

To convert grams into moles, use Grams To Moles Calculator.

What is Chemical Reaction?

Chemical reaction is an transformation process in which 2 or more substances are transformed from one form to the other. After this, reactants are transformed to products or other substances.

What are Reactants?

Reactants take a part in the chemical reaction and reactants are the substances which are combined with each other to make new substance or products.

What is Catalyst?

Catalyst is a substance which is added to increase the rate of a chemical reaction. A catalyst does not consume itself in the chemical reaction but it increases its efficiency.

What is the significance of Moles?

Having the known value of moles of the substances that combine to form a solution/mixture or a product can assist you in figuring out the ratio of the reactant substances. It further helps to increase efficiency also.

What is 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. Therefore, we can say that Mole Fraction equation is the ratio of the reactant substances that react/combine to form a product.

Why it is Necessary to Know Mole Fraction of a Chemical Reaction?

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.

How to calculate Mole Fraction?

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 equation by just giving 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 1.33 moles of hydrogen and 0.6 atoms of oxygen in a water molecule then you can calculate the molar fraction of each reactant (hydrogen and oxygen) using the molar fraction formula as:

$$\frac{1.33mol}{1.93mol} = 0.68$$

$$\frac{0.6mol}{1.93mol} = 0.31$$

So, 0.68 is the molar fraction of hydrogen, and 0.31 is the molar fraction of oxygen in a water molecule.

(Whereas, 1.93 is the total number of moles of the reactants:1.33mol+0.6mol= 1.93mol)

To calculate the molar fraction of any substance, all you have to do is to know the value of the moles of the respective substance.

How to use Mole Fraction Calculator?

Although you can calculate the molar fraction manually using mole fraction formula, but it can be time-consuming. You can learn how to find mole fraction by using mole fraction calculator.

Follow these directions to use Mole Fraction Calculator:

  • First Step: Place the number of moles of the substance (the molar fraction of which you want to calculate) in the box "ELEMENT WEIGHT"
  • Second Step: Place the number of moles of the other substance involved in the chemical reaction in the box titled "DISSOLVED IN"
  • Third Step: Press CALCULATE to find out the molar fraction.

Mole fraction calculator uses mole fraction formula to work. You just have to place the number of moles of the substances, respectively as per the given directions.

Let's solve an example while using mole fraction calculator.

Example 1:

To check molar fraction of hydrogen, enter number of moles of hydrogen (1.33mol) in first box and the number of moles of Oxygen (0.6mol) in the second Box.

After clicking the Calculate Button, molar fraction calculator will give you the molar fraction of Hydrogen as (0.68).

Example 2:

To check molar fraction of oxygen in water, enter number of moles of oxygen (0.6mol) in the first box and the number of moles of hydrogen in thee second box.

After clicking the Calculate Button, mole fraction calculator will give you the molar fraction of oxygen as (0.31).

We hope our Molar Fraction Calculator will help you a lot, so, all the best for your chemical equations things!
