Hello there!
In this case, according to the given chemical reaction and the fact that 22.4 L of a gas are occupied by 1 mol at standard pressure and temperature conditions, it will be possible for us to calculate the number of molecules of propane, by using the Avogadro's number, the 1:3 mole ratio with carbon dioxide and the aforementioned volume-mole ratio to obtain:

The binding energy is calculated from the product of the mass defect and the square of the speed of light. First, we need to calculate for the mass defect. We do as follows:
m = mass products - mass of reactantsm = 33*1.00867 + 27*1.00728 - 59.9338 m = 0.54887
E = mc^2 = 0.54887 (3x10^8)^2 = 4.94x10^16 J
