The image above represents the mass concentration.

To compute for mass concentration, two essential parameters are needed and these are **molar concentration (c)** and **molar mass (M)**.

ρ = c x M

Where;

ρ = mass concentration

c = molar concentration

M = molar mass

Let’s solve an example;

Find the mass concentration when the molar concentration is 24 and molar mass is 15.

This implies that;

c = molar concentration = 24

M = molar mass = 15

ρ = c x M

ρ = 24 x 15

ρ = 360

Therefore, the mass concentration is 360 Kg/dm³.

**Calculating the Molar Concentration when the Mass concentration and Molar Mass.**

c = ^{ρ} / _{M}

Where;

c = molar concentration

ρ = mass concentration

M = molar mass

Let’s solve an example;

Find the molar concentration when the mass concentration is 120 with a molar mass of 40.

This implies that;

ρ = mass concentration = 120

M = molar mass = 40

c = ^{ρ} / _{M}

c = ^{120} / _{40}

c = 3

Therefore, the **molar** **concentration** is **3 mol/L.**

**Calculating the Molar Mass when the Mass concentration and Molar Concentration .**

M = ^{ρ} / _{c}

Where;

M = molar mass

ρ = mass concentration

c = molar concentration

Let’s solve an example;

Find the molar mass when the mass concentration is 150 with a molar concentration of 30.

This implies that;

ρ = mass concentration = 150

c = molar concentration = 30

M = ^{ρ} / _{c}

M = ^{150} / _{30}

M = 5

Therefore, the **molar mass** is **5 mol.**
