Consider the combustion of propane:
C3H8(g) + 5O2(g) ----3CO2 + 4H2O (l) delta H = 2221 kJ
A balloon is being inflated to its full extent by heating the air inside it. In the final stages of this process, the volume of the balloon changes from 4.00 x 10^6 L to 4.50 x 10^6 L by the addition of J energy as heat. Assume that all the heat comes from the combustion of propane. What mass of propane must be burned to furnish this amount of energy assuming the heat transfer process is 50.% efficient?
