sodium azide, decomposes according to the following equation: 2NaN3 (s) -> 2Na (s) + 3N2(g)

Question

What mass of sodium azide is required to provide nitrogen needen to inflate a 80.0 L bag to a pressure to 1.35 atm at 25 c?

Answer 1

Use PV = nRT and calculate n, number of moles.
Using the coefficients in the balanced equation, convert moles N2 to moles NaN3.

Now convert moles NaN3 to grams. g = moles x molar mass.
