Question
Automobile air bags inflate following a serious impact. The impact triggers the chemical reaction:$$2 \mathrm{NaN}_{3}(s) \rightarrow 2 \mathrm{Na}(s)+3 \mathrm{~N}_{2}(g)$$If an automobile air bag has a volume of $11.8 \mathrm{~L}$, what mass of $\mathrm{NaN}_{3}$ (in g) is required to fully inflate the air bag upon impact? Assume STP conditions.
Step 1
We can do this using the molar volume of a gas at STP, which is 22.4 L/mol. So, we have: $$ \frac{11.8 \, \text{L}}{22.4 \, \text{L/mol}} = 0.527 \, \text{mol} \, \text{N}_2 $$ Show more…
