Describe how you could make 40 mL of a 3% (m/v) {eq}CuSO_4 {/eq} solution.

## Question:

Describe how you could make 40 mL of a 3% (m/v) {eq}CuSO_4 {/eq} solution.

## Preparation of Solutions:

The calculation needed for the preparation of solutions requires a series of unit conversions to allow the given value to express to the desired units. As an example, if given a solution with a concentration in molarity, the volume will be multiplied first on the concentration to cancel the unit L followed by the multiplication by the molar mass to convert moles to mass.
