This problem involves applying gas laws to design an airbag for a car, which must be filled with gas at a specific pressure of 829 mm Hg and temperature of 22°C. The airbag has a volume of 45.5 L. To generate the required nitrogen gas, we need to calculate the quantity of sodium azide (NaN₃) required for the reaction: 2 NaN₃ → 2 Na + 3 N₂. This practical application of chemistry will illustrate the use of the ideal gas law and stoichiometry in real-world scenarios.
