# What does the molarity of a solution indicate?

$\text{Molarity}$ $=$ $\text{Moles of solute"/"Volume of Solution}$
Or $C \left(\text{concentration}\right) = \frac{n}{V}$, where $n$ is the amount of substance in moles, and $V$ is the volume of the solution.
The units of concentration are simply $m o l \cdot {L}^{-} 1$. And thus $\text{volume "xx" concentration}$ $=$ $n$, i.e. moles of solute. Doing calculations myself, I still use the relationship $C = \frac{n}{V}$ habitually to do stoichiometry problems.
