The $\text{concentration..........}$

#### Explanation:

There are different expressions $\text{for concentration}$: $\text{parts per million"; "percentage by mass"; "molality"; "molarity}$....

Perhaps the most useful term is $\text{molarity}$.............where

$\text{Molarity"="Moles of solute"/"Volume of Solution}$.

This expresses the amount of substance per unit volume of the solution....
