# What is the molarity of .450 mol of NaOH in 1.65 L of solution?

$\text{Concentration"="Moles of solute"/"Volume of solution}$
$\text{Concentration} = \frac{0.450 \cdot m o l}{1.65 \cdot L}$ $\cong$ $0.3 \cdot m o l \cdot {L}^{-} 1$ with respect to sodium hydroxide. What is the $p H$ of this solution?
