NaN3 decomposes to form Na and N as shown in the equation 2NaN3 ---> 2Na + 3N2. The N produced inflates the airbag to a volume of 7.50 x 10^-2 m^3 at a pressure of 150kPa and temperature of 35ºC. Calculate the minimum mass of NaN3 that must decompose
pV =nRT ==> n = pV/RT . n = ((150x10^3) x (7.5x10^-2)) / (8.31 x 308) = 4.395 Mole NaN3: 4.395 x 2/3 = 2.93 min. mass NaN3: 2.93 x (23+14x3) = 190g
