Problem Details

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 N(28.02 g/mol)?

(A) 1.01 × 103

(B) 8.12 × 102

(C) 5.41 × 102

(D) 2.26 × 10

(E) 1.22 × 103 g
