What is the mass of sodium azide required to decompose and produce 15.346 moles of nitrogen

The heat generated causes sodium azide to decompose into sodium metal and nitrogen gas, which inflates the car's air bags. Under normal circumstances, this molecule is quite stable. If heated, though, it will fall apart. The chemical equation 2 NaN3 --> 2 Na + 3 N2 describes exactly how it falls apart.
