Air bags in automobiles contain crystals of sodium azide (nan3) which, during a collision, decompose rapidly to give nitrogen gas and sodium metal. (potassium nitrate and silicon dioxide are added to remove the sodium metal by converting it into a harmless material.) the nitrogen gas liberated behaves as an ideal gas and any solid produced has a negligible volume (its volume can be ignored). calculate the mass of sodium azide required to generate enough nitrogen gas to fill a 57.0 l air bag at 1.04 atm and 16°c. report your answer in grams of nan3 to the nearest whole number.
