Mole Ratio Calculator

This online mole ratio calculator will let you calculate the ratio of moles between the different reacted chemicals and different chemical products. You can also determine the molar mass or the number of moles (molecules) of each chemical required to carry out complete the reaction process by using our molar ratio calculator.

Let’s move on! To understand the concept of mole ratio with particular formulas, steps to calculate the mole ratio with solved examples.

What is a mole ratio?

In chemistry, molar or mole ratio can be defined as:

“The comparison between the number of moles of the reactants utilized and the number of moles of products produced in a balanced chemical reaction”

Since mole ratio can be expressed as a reactant and product in a chemical reaction. Therefore, it is also known as the mole-to-mole ratio. Users can also perform calculations regarding mass ratio parameters easily by using an online mass ratio calculator.

Mole ratio formula:

Mole ratio = ( [Combustion amount of 2nd element] / [Molar mass of second element] ) / ( [Combustion amount of 1st element] / [Molar mass of first element] )

Moreover, you can determine moles, moles of solute, and moles of solvent to the chemical solution by using an online mole fraction calculator.

Mole Ratio Example:

When 30 moles of hydrogen react with 10 moles of nitrogen during ammonia production. The reaction gives 20 moles of ammonia giving the molar ratio between different participants. These include as:

10 mol N2 / 30 mol H2 = 1/3

20 mol NH3 / 30 mol H2 = 2/3
​
20 mol NH3 /10 mol N = 2/1

Mole Ratio Units:

In SI units, mole ratio units are expressed as a mole itself. Since it has no dimension number as the units cancel out each other.
​If you want to calculate how much of each element is present in molar mass, you can now use an online molar mass calculator to perform calculations swiftly.

How to calculate mole ratio?

Now you can easily find out the mole ratio between two elements in a chemical reaction while using our online mole ratio calculator with the following requirements including:
Firstly, you need to equal or balance the given chemical reaction
After that, attain the coefficient of the corresponding elements in the balanced equation
Now you are enabled to calculate the ratio between these coefficients

In other words, the formula to calculate the molar ratio between two elements is given as:

A: B = Coefficient of A / Coefficient of B

where:

• “A” represents an element that reacted or was produced during the reaction
• “B” also represents an element that reacted or was produced during the reaction
• “Coefficient of A” represents as the balanced chemical reaction
• “Coefficient of B” also represents as the balanced chemical reaction

The coefficient in a balanced chemical reaction will be helpful to estimate the molar ratio since the coefficient represents the number of molecules of that element that is needed for the reaction to occur without leaving any excess of the reactants.

Example:

Consider the following balanced chemical equation of hydrogen and oxygen is given as: :
2H 2 + O2 → 2H2O
From the above, the coefficients in this balanced chemical reaction conclude the following information that includes:

• Two molecules of hydrogen(H2) take one molecule of oxygen (O2) to react completely
• Two molecules of hydrogen(H2) react to form two molecules of water (H2O)
• Every molecule of oxygen (O2) reacts to form two molecules of water (H2O)

The above result represents whether we have twenty molecules of hydrogen, then we will need ten molecules of oxygen to react with it to form twenty molecules of water.

In a balanced chemical reaction, the ratio between the number of molecules has different reactants and products. One mole of a substance is represented by 6.02214076 * 10^23 which is equal to a number of atoms or molecules. Our online mole ratio calculator allows you to clarify your concepts regarding mole of substance problems.
Also, you can use the grams to moles calculator to make calculations regarding the parameters of the number of moles instantly with accurate results.

Solved Examples:

Now we will resolve some examples using a molar ratio calculator chemistry to clarify your concept and calculations. Let’s move on!
Example #1:

Consider a chemical equation , N2 + 3H2 = 2NH3. How to find mole ratio of N2 and H2 if it has the combustion of 2.9 g of N and 3.5 g of H2?

Solution:

Molar Mass of the Nitrogen (N) =14

Molar mass of N2 = 14 x 2 = 28

Molar Mass of H =1.008

Molar mass of H2 = 1.008 x 2 =2.0

Substituting the given values in the mole ratio formula,

= [ ( 3.5 / 2.0) / ( 2.9 / 28 ) ]

= [ 1.75 / 0.103 ]

=16.99

Therefore, the molar ratio is 1: 16.99

Example #2:

How to find molar ratio of Fe molecules if it will react with 0.27 moles of O2 molecules in the given equation?

4Fe + 3O2 → 2Fe2O3

Solution:

Chemical reaction is given as: 4Fe + 3O2 → 2Fe2O3

Generally, 4 moles of Fe react with 3 moles of O2 which produces 2 moles of Fe2O3

Therefore, Molar ratio of Fe and O2 = Fe : O2 = 4:3
