$\text{A solution......}$

#### Explanation:

And a binary solution consists of TWO components, $\text{the solvent}$, (generally the species in excess), and $\text{the solute}$. There are various ways to measure the concentration of solution; most commonly, we calculate the $\text{molarity}$.

$\text{Molarity"="Moles of solute"/"Volume of solution}$..with associated units of $m o l \cdot {L}^{-} 1$...

..alternatively...$\text{Molality"="Moles of solute"/"kilograms of solvent}$..with associated units of $m o l \cdot k {g}^{-} 1$...

..for dilute AQUEOUS solutions, $\text{molarity "-=" molality}$
