Solution: Automobile air bags inflate following a serious impact. The impact triggers the chemical reaction:  2 NaN3(s) →  2Na(s) + 3 N2(g) If an automobile air bag has a volume of 11.8 L, what mass of NaN 3 (in g) is required to fully inflate the air bag upon impact? Assume STP conditions.   

Problem

Automobile air bags inflate following a serious impact. The impact triggers the chemical reaction: 

2 NaN3(s) →  2Na(s) + 3 N2(g)

If an automobile air bag has a volume of 11.8 L, what mass of NaN 3 (in g) is required to fully inflate the air bag upon impact? Assume STP conditions.
