A car air bag requires 70. L of nitrogen gas to inflate properly. The following equation represents the production of nitrogen gas:

2NAN subscript 3 yielding 2NA + 3N subscript 2

the density of nitrogen gas is typically 1.16 g/L at room temperature. How would you calculate the number of grams of Nitrogen that is needed to inflate the air bag?

First let me point out that NAN3 is NOT the same as NaN3 and NA is not the same as Na.
2NaN3 ==> 2Na + 3N2

How about 1.16 g/L x 70 L = ?? g.
