I Need Help On Chemistry Gas Laws, Conversions, Etc.?

Here’s my question.
It has recently been brought to our attention that our side-impact
airbags are insufficient. We have redesigned the side-impact airbag.
Our new air bags contain a volume of 58 liters when inflated. We have
determined that the decomposition of sodium azide (NaN3) is the best
method for rapidly producing nitrogen gas to fill the airbags. Please
determine the initial mass of sodium azide needed to fill the 58 liter side
impact airbag with nitrogen to a pressure of 1100 mm Hg. You must
make sure you take into account that the heat released by the
decomposition reaction will increase the temperature of the gas inside
the airbag to 76 ˚C. Our reaction specialists determined that the
decomposition of sodium azide follows the following unbalanced
chemical formula:
NaN3(s) Na(s) + N2(g)
