Problem

Air bags are activated when a severe impact causes a steel ball to compress a spring and electrically ignite a detonator cap. This causes sodium azide (NaN3) to decompose explosively according to the following reaction:

2NaN3(s) → 2Na(s) + 3N2(g)

What mass of NaN3(s) must be reacted to inflate an air bag to 70.0 L at STP?
