  Sodium azide is an ionic compound found within the airbags cf, w)s,*gpcgof some older cars. The airbag is deployed as a safety feature in the event of an accident. In this application, the sodium azide decomposes rapidly, and the gas sfgw,cg,*) pc formed inflates the airbag.
The decomposition of sodium azide under these conditions is given below.
$2NaN_{3(s)}\rightarrow2Na (s)+3 N_{2(g)}$
1.Suggest the formula and charge for the azide ion.
2.A typical airbag requires $65.0dm^3$of nitrogen gas for complete inflation at STP. Using section 2 of the data booklet, calculate the mass of sodium azide that the airbag must contain for this purpose.Molar mass for sodium azide calculated=  $g mol^{-1}$
