Ideal Gas: Reaction Stoichiometry And Mass Of Reagent To Volume Confused?
May 12th, 2009
Automobile airbags are inflated by nitrogen gas, generated from the explosive decomposition of solid sodium azide:
2NaN3 2Na + 3N2
What volume of N2 at 20°C and 1.05 atm pressure can be produced from the decomposition of 44.8 g of NaN3?

Moles NaN3 = 44.8 g / 65.01 g/mol =0.689
the ratio between NaN3 and N2 is 2 : 3
moles N2 produced = 0.689 x 3 / 2 =1.03
T = 20 + 273 = 293 K
V = nRT / p = 1.03 x 0.0821 x 293 / 1.05 =23.7 L
