# An NaOH solution contains 1.90 mol of NaOH, and its concentration is 0.555 M. What is its volume?

Jan 26, 2016

The volume is $\text{3.42 L}$.

#### Explanation:

First rewrite the molarity of NaOH, $\text{0.555 M}$, as $\text{0.555 mol/L}$.

Next divide the given moles NaOH by the molarity of the solution in mol/L.

$\cancel{\text{1.90mol NaOH"xx("1L NaOH")/(cancel"0.555 mol NaOH")="3.42 L}}$
