The equation for the rapid thermal decomposition of sodium azide in a vehicle's airbag safety system is:
2NaN3(s)→2Na(s)+3N2(g)2\text{NaN}_3(\text{s}) \rightarrow 2\text{Na}(\text{s}) + 3\text{N}_2(\text{g})2NaN3(s)→2Na(s)+3N2(g)
An airbag inflator containing 3.25 g of solid sodium azide (NaN3\text{NaN}_3NaN3) undergoes complete decomposition.
Calculate the maximum volume of nitrogen gas (N2N_2N2) in dm3\text{dm}^3dm3, measured at room temperature and pressure, produced during this inflation process.
(relative formula mass: NaN3=65\text{NaN}_3 = 65NaN3=65, 1 mol of any gas at room temperature and pressure occupies 24 dm3)
