Use stoichiometry to determine how much grams of NaN3 is needed to produce 350 g N2
It can be seen in the balanced equation that 2 moles of NaN3 produces 3 moles of N2
Automotive air bags inflate when sodium azide, NaN3, rapidly decomposes into its component elements:
2 NaN3(s) → 2 Na(s) + 3 N2(g)
How many grams of NaN3 (65.02 g/mol) are needed to produce 350. g of N2 (28.02 g/mol)?
(A) 1.01 × 103 g
(B) 8.12 × 102 g
(C) 5.41 × 102 g
(D) 2.26 × 102 g
(E) 1.22 × 103 g
