Automotive air bags inflate when a sample of sodium azide nan3 is very rapidly decomposed.
2nan3 ? 2na +3n2
what mass of sodium azide is required to produce 2.6 feet3 (736 l) of nitrogen gas with the density of 1.25 g/l?

1424 grams

Explanation:

Thus mass of nitrogen produced is 920 g.

According to stoichiometry:

3 mole of are produced from= 2 mole of

Thus 32.8 moles of are produced from= of

Mass of

Thus 1424 grams of sodium azide is required to produce 736 L of Nitrogen gas with the density of 1.25 g/L.
