Use PV = nRT. Substitute and solve for n = number of mols.
Then use the coefficients in the balanced equation to convert mols N2 to mols NaN3.
Finally, g NaN3 = mols NaN3 x molar mass NaN3.

In the chemical reaction used in automotive air-bag safety systems, nitrogen gas is produced by the decomposition of sodium azide as described in the reaction below.
NaN3(s) Na(l) + N2(g)
What mass of NaN3 must be decomposed to generate enough nitrogen gas at 25.0 oC and 0.980 atm to fill an airbag with a volume of 5.0 x 104 cm3
