The image above represents the molar mass of a substance.

To compute for the molar mass, two essential parameters are needed and these parameters are **mass (m)** and **number of moles (n).**

The formula for calculating the molar mass:

M = ^{m} ⁄ _{n}

Where;

M = Molar mass

m = Mass

n = Number of moles

Let’s solve an example;

Find the molar mass of a substance with a mass of 14 kg and number of moles of 28 mol.

This implies that;

m = Mass = 14

n = Number of moles = 28

M = ^{m} ⁄ _{n}

M = ^{14} ⁄ _{28}

M = 0.5

Therefore, the **molar mass** is **0.5 Kg/mol.**

**Calculating the Mass of a Substance when the Molar Mass and the Number of Moles is Given.**

m = nM

Where;

m = Mass

n = Number of moles

M = Molar Mass

Let’s solve an example;

Find the mass of a substance with a molar mass of 30 Kg/mol and number of moles of 15 mol.

This implies that;

n = Number of moles = 15

M = Molar Mass = 30

m = nM

m = 15 x 30

m = 450

Therefore, the **mass of a substance** is **450 kg.**

**Calculating the Number of Moles of a Substance when the Molar Mass and the Mass is Given**

n = ^{m} / _{M}

Where;

n = Number of moles

m = Mass

M = Molar Mass

Let’s solve an example;

Find the number of moles of a substance with a mass of 22 kg and molar mass of 40 Kg/mol.

This implies that;

m = Mass = 22

M = Molar Mass = 40

n = ^{m} / _{M}

n = ^{22} / _{40}

n = 0.55

Therefore, the **number of moles** is **0.55 mol.**
