Automotive air bags inflate when a sample of sodium azide, NaN3, is very rapidly decomposed.
2NaN3(s) ⟶ 2Na(s) + 3N2(g)
What mass of sodium azide is required to produce 2.6 ft3 (73.6 L) of nitrogen gas with a density of 1.25 g/L?
We can use the density and the volume provided to get the mass of N2
We will be using the V in L instead of ft3
The mass of N2 will be used to find the moles of sodium azide and eventually the mass
