$359gO_{2}$

Explanation:

1. Write the balanced equation:

$_{2}H_{2}+O_{2}=_{2}H_{2}O$

2. Find the quantity of $H_{2}O$ produced by 45.2g of hydrogen:

$45.2gH_{2}*\frac{1molH_{2}}{2.016gH_{2}}*\frac{2molesH_{2}O}{2molesH_{2}}*\frac{18gH_{2}O}{1molH_{2}O}= 404gH_{2}O$

So, 45.2g of $H_{2}$ produce 404g of $H_{2}O$

3. Find the quantity of $O_{2}$ that reacted with 45.2g of $H_{2}$ :

$404gH_{2}O*\frac{1molH_{2}O}{18gH_{2}O}*\frac{2molesO_{2}}{2molesH_{2}O}*\frac{16gO_{2}}{1molO_{2}}=359gO_{2}$
