Question:
Air bags in automobiles contain sodium azide, NaN3, which decomposes rapidly during a collision to give nitrogen gas and sodium metal. The nitrogen gas liberated by this process instantly inflates the air bag. Assume that the nitrogen gas liberated behaves as an ideal gas and that any solid produced has a negligible volume (which may be ignored).
(a) Calculate the mass (in grams) of sodium azide required to generate enough nitrogen gas to fill a 57.0-L air bag at 1.37 atm and 25.0°C.
(b) What is the root mean square speed of the N2 gas molecules that are generated?
