Relating Gas Variables and Reaction Stoichiometry

Automobile air bags are inflated by nitrogen gas generated by the rapid decomposition of sodium azide. NaN3:

2 NaN3(sj—2 Na(s) + 3 N2(g)

If an air bag has a volume of 36 L and is to be filled with nitrogen gas at 1.15 atm and 26 °C, how many grams of NaN3 must be decomposed?

In the first step of the industrial process for making nitric acid, ammonia reacts with oxygen in the presence of a suitable catalyst to form nitric oxide and water vapor

4 NH3(g) + 5 02(g)-4 NO(g) + 6 H20(g)

How many liters of NH3(g) at 850 °C and 5.00 atm are required to react with 1.00 mol of 02(g) in this reaction?
