The air bags in automobiles were once inflated by nitrogen gas generated by the rapid decomposition of sodium azide, NaN3. 2 NaN3(s) → 2 Na(s) + 3 N2(g) If an air bag has a volume of 43.8 L and is to be filled with nitrogen gas at a pressure of 1.13 atm at a temperature of 22.4˚C, how many moles of NaN3 must decompose? You may assume the N2 behaves as an ideal gas.
