Ammonia (NH3) is an important compound since it is used in large amounts for the manufacture of nitrogenous fertilizers, nylon and many other important
compounds. It is manufactured industrially by the catalytic reaction between nitrogen between nitrogen and hydrogen, according to the following equation,
N2(g) + H2(g) = NH;(g)

The design of air-bag depends on stoichiometric precision.
The following reaction takes place when the air-bag is inflated.
2 NaN3 (s) → 2 Na(s) + 3 N2 (g)
6Na(s) + Fe2O3(s) → 3NA2O(s) + 2Fe
Assume that 43.4 L of nitrogen gas are needed to inflate an air bag to the proper size.
(A) How many grams of NaN3 must be included in the air-bag to generate this amount of nitrogen gas?
(The density of nitrogen gas at this temperature is 0.916 g/L).
(B) How much Fe2O3 (in grams) must be added to the air-bag for this amount of NaN3?
Use the following molar masses:
N2 = 28.02 g/mol
NaN3 = 65.01 g/mol
Fe203 = 159.69 g/mol
