1. (MC) Automobile air bags use the decomposition of sodium azide as their source of gas for
2 NaN3 (s) - 2 Na (s) + 3 N2 (g).
What mass (g) of NaN3 is required to provide 40.0 L of N2 at 25.0 C and 763 torr?
(a) 1.64
(b) 1.09
(c) 160
(d) 71.1
(e) 107

its correct option is d)71.1... View the full answer

Salution, the gluenean is
2 NON3 (S) - 2 Nacsat 3 N2 68)
given V = UOL
T= 273+25 = 2 92K
P = 763 Tan = 763= 1003 atm
