$\text{0.500 mol Na"_2"O"_2}$ will be needed to react with excess water to produce $\text{1.00 mol NaOH}$.

#### Explanation:

Balanced Equation

$\text{2Na"_2"O"_2 + "2H"_2"O}$$\rightarrow$$\text{4NaOH + O"_2}$

Mole ratio between $\text{Na"_2"O"_2}$ and $\text{NaOH}$.

$\left(2 \text{mol Na"_2"O"_2)/(4"mol NaOH}\right)$ and $\left(4 {\text{mol NaOH")/(2"mol Na"_2"O}}_{2}\right)$

Multiply given mol $\text{NaOH}$ by the mole ratio with $\text{Na"_2"O"_2}$ in the numerator.
