calculate the Mr of NAN3 ...Most modern cars are fitted with airbags. These work by decomposing sodium azide to liberate
nitrogen gas, which inflates the bag.
2NaN3 3N2 + 2Na
A typical driver’s airbag contains 50 g of sodium azide.
Calculate the volume of nitrogen this will produce at room temperature.
A 9.2 dm3 B 13.9 dm3 C 27.7 dm3 D 72.0 dm3
caculate the moles of NaN3 in 50 g of NaN3 by 50/Mr
use the ratio method to calculate the moles of N2 produced
if 2 mole of NaN3 produces 3 moles of N2 then how many moles will (calculated moles) produce?
calculate the volume using the molar gas volume:
moles * 24 = volume of N2
