The image above represents the mass concentration.

To compute the mass concentration, two essential parameters are needed and these parameters are **mass (m) **and **volume (V).**

The formula for calculating mass concentration:

ρ = ^{m} ⁄ _{V}

Where;

ρ = Mass concentration

m = Mass

V = Volume

Let’s solve an example;

Find the mass concentration when the mass is 8 kg with a volume of 24 dm³.

This implies that;

m = Mass = 8

V = Volume = 24

ρ = ^{m} ⁄ _{V}

ρ = ^{8} ⁄ _{24}

ρ = 0.33

Therefore, the **mass concentration** is **0.33 Kg/dm³.**

**Calculating the Mass when the Mass Concentration and the Volume is Given.**

m = Vρ

Where;

m = Mass

ρ = Mass concentration

V = Volume

Let’s solve an example;

Find the mass when the mass concentration is 12 kg/dm³ with a volume of 7 dm³.

This implies that;

ρ = Mass concentration = 12

V = Volume = 7

m = Vρ

m = 12 x 7

m = 84

Therefore, the **mass concentration** is **84 kg.**

**Calculating the Volume when the Mass Concentration and the Mass is Given.**

V = ^{m} / _{ρ}

Where;

V = Volume

m = Mass

ρ = Mass concentration

Let’s solve an example;

Find the volume when the mass concentration is 18 kg/dm³ with a mass of 32 kg.

This implies that;

ρ = Mass concentration = 18

m = Mass = 32

V = ^{m} / _{ρ}

V = ^{32} / _{18}

V = 1.77

Therefore, the **volume** is **1.77 dm ^{3}.**
