The image above represents the volume concentration.

To compute the volume concentration of a substance, two essential parameters are needed and these parameters are **volume of the constituent (V _{i})** and

**volume of the mixture (V).**

The formula for calculating volume concentration:

φ = ^{Vi} ⁄ _{V}

Where;

φ = Volume concentration

V_{i} = Volume of the constituent

V = Volume of the mixture

Let’s solve an example;

Find the volume concentration with a volume of the constituent of 23 and a volume of the mixture of 32.

This implies that;

V_{i} = Volume of the constituent = 23

V = Volume of the mixture = 32

φ = ^{Vi} ⁄ _{V}

φ = ^{23} ⁄ _{32}

φ = 0.718

Therefore, the **volume concentration** is **0.718.**

**Calculating the Volume of the Constituent when the Volume Concentration and the Volume of the Mixture is Given.**

V_{i} = Vφ

Where;

φ = Volume concentration

V = Volume of the mixture

Let’s solve an example;

Find the volume of the constituent with a volume concentration of 18 and a volume of the mixture of 22.

This implies that;

φ = Volume concentration = 18

V = Volume of the mixture = 22

V_{i} = Vφ

V_{i} = 18 x 22

V_{i} = 396

Therefore, the **volume of the constituent** is **396 cm ^{3}.**
