Problem
An automobile airbag is inflated by the thermal decomposition of solid sodium azide according to the reaction 2 NaN₃(s) → 2 Na(s) + 3 N₂(g). An airbag requires a pressure of 1.30 atm of nitrogen gas at 298 K to deploy properly. If 65.0 g of sodium azide is completely decomposed at 298 K, calculate the final volume of the inflated airbag.
(1) Calculate the number of moles of nitrogen gas produced by the decomposition of 65.0 g of sodium azide.
(2) Determine the volume, in liters, that the nitrogen gas will occupy at 1.30 atm and 298 K.
