Airbаgs rаpidly prоduce nitrоgen gаs thrоugh reactions like this one: 2 NaN3 (s) → Na (s) + 3 N2 (g) In this reaction, what volume (in liters) of nitrogen gas can be produced by the reaction of [x] g of NaN3 if the temperature is [y] K and the pressure is 1.2 atmospheres? The formula mass of NaN3 = 65.02 g/mol.
