Need help answering this question can you please show step by step on how to solve this problem. The answer needs to be in grams.
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.
2 NaN3(s) 2 Na(s) + 3 N2(g)
What mass of NaN3(s) must be reacted to inflate an air bag to 72.0 L at STP?
