Dilution is the addition of solvent, which decreases the concentration of the solute in the solution.

Concentration on the other hand, is the removal of solvent, which increases the concentration of the solute in the solution.

How to calculate volume of solution when it is diluted?

The volume of solution needed to make the solution can be calculated by the formula,

V1 x N1 = V2 x N2

4 ml of 1:80 diluted solution has to be made from 1:4 solution.

Applying these values in the above formula,

V1 x (1/4) = 4 x (1/80)

V1/4 = 1/20

V1 = 4/20

V1 = 0.2 ml
