2NaN3 ==> 2Na + 3N2
Use PV - nRT and solve for n at the conditions listed.
Convert mols N2 needed to mols NaN3 needed. Then grams NaN3 = mols NaN3 x molar mass NaN3.
How many grams of NaN₃ must be decomposed to fill a 42.0 L airbag with nitrogen gas at a pressure of 1.05 atm and a temp of 29.5 degrees Celsius?
