Air bags are activated while a severe impact causes a steel ball to compress a spring as well as electrically ignite a detonator cap. This action causes sodium azide(NaN3) to decompose explosively according to the subsequent reaction.
2 NaN3(s) 2 Na(s) + 3 N2(g)
Explain what mass of NaN3(s) must be reacted to inflate an air bag to 66.7L at STP?
