# If 18.25 g HCl is dissolved in enough water to make 500.0 mL of solution, what is the molarity of the HCl solution?

$1 \cdot m o l \cdot {L}^{-} 1$.
$\text{Molarity}$ $=$ $\text{Moles of solute (moles)"/"Volume of soltion (L)}$
$=$ $\frac{18.25 \cdot g}{36.50 \cdot g \cdot m o {l}^{-} 1} \times \frac{1}{0.500 L}$ $=$ $1.00 \cdot m o l \cdot {L}^{-} 1$
