Chapter 9, Problem 9.57AQAP

When hydrogen peroxide $\left(H_2{O}_2\right)$ is used in rocket fuels, it produces water and oxygen $\left(O_2\right)$ . (9.2, 9.3)

$2H_2{O}_2\left(l\right)\to 2H_{2}O\left(l\right)+O_2\left(g\right)$

1. How many moles of $H_2{O}_2$ are needed to produce 3.00 mol of $H_{2}O$?
2. How many grams of $H_2{O}_2$ are required to produce 36.5 g of $O_2$?
3. How many grams of $H_{2}O$ can be produced when 12.2 g of $H_2{O}_2$ reacts?
