Automobile air bags use the decomposition of sodium azide as their source of gas for rapid inflation: 2NaN3 (s) → 2Na (s) + 3N2 (g). What mass (g) of NaN3 is required to provide 26.5 L of N2 at 22.0°C and 1.10 atm? A) 52.2 B) 700. C) 0.807 D) 1.21 E) 1.10 ***what I have so far*** PV = nRT P = 1.10 atm n = (1.10 x 26.5) / (0.0821 x 295) V = 26.5 L n = 26.5 / 24.22 n = PV / RT = 0.0012 n = 1.094 R = 0.0821 T = 295 K 2 mol NaN3 → 3 mol N2

Automobile air bags use the decomposition of sodium azide as their source of gas for rapid
inflation: 2NaN3 (s) → 2Na (s) + 3N2 (g). What mass (g) of NaN3 is required to provide 26.5 L of N2 at 22.0°C and 1.10 atm?
- A) 52.2 B) 700. C) 0.807 D) 1.21 E) 1.10
***what I have so far***
PV = nRT
P = 1.10 atm n = (1.10 x 26.5) / (0.0821 x 295)
V = 26.5 L n = 26.5 / 24.22
n = PV / RT = 0.0012 n = 1.094
R = 0.0821
T = 295 K
2 mol NaN3 → 3 mol N2
*** not sure where to go from here***
