2NaN3(s) -> 2Na(s) + 3N2(g)

What mass of sodium azide should be loaded in the device to ensure full inflation of the same air bag if the actual reaction can be expected to proceed to give only 83% yield of nitrogen gas?

  2. Sorry, I have forgotten to give the information. This question has part a, which is "What mass of sodium azide must be completely reacted to inflate an air bag to 65.0 liters at 20.0 ºC and 1.06 atm?"

    Please help me because I have calculated many time, but still cannot get the correct answer, thank you.
