Question

Airbags used in automobiles are inflated with nitrogen gas (28.01 g/mol) produced from the reaction of sodium azide (NaN3, 65,01 g/mol) and excess iron(III) oxide (Fe2O3, 159.69 g/mol) as shown in the following equation:

6NaN3(s) + Fe2O3(s) ➜ 3Na2O(s) + 2Fe(s) + 9N2(g)

An airbag contains 40.0 L of nitrogen gas at 1.10 atm and 25.0 ºC. How many grams of sodium azide is needed to completely produce all of the nitrogen in the presence of excess iron(III) oxide?
