Use stoichiometry to determine the mass of NaN_{3} needed to produce 25 g N_{2}

Find the molar mass of NaN_{3} and N_{2} for the dimensional analysis

Automotive air bags inflate when sodium azide decomposes explosively to its constituent elements:

2NaN_{3}(s) → 2Na(s) + 3N_{2}(g)

How many grams of sodium azide are required to produce 25.0 g of nitrogen?

A) 1.34

B) 58.0

C) 87.0

D) 38.7

E) 0.595
