INTERACTIVE EXAMPLE Gas Laws and Stoichiometry You are asked to design an air bag for a car. You know that the bag should be filled with gas with a pressure higher than atmospheric pressure, say 842 mm Hg, at a temperature of 22.0 °C. The bag has a volume of 41.5 L. What quantity of sodium azide, NaN3, should be used to generate the required quantity of gas? The gas-producing reaction is 2 NaN3(s) - 2 Na(s) + 3 N₂(g) 9
