The heat of combustion for one mole of alcohol.

Chemistry coursework
My aim is to find the molar heat of combustion of ethanol, propanol and butanol .I will also be comparing the experimental molar heat of combustion with the theoretical, using bound enthalpy's.
Background information
I have found some information that will help me with my experiment. This text is all from www.webchem.net
The complete combustion of propane can be represented by the following equation:
or we could redraw it to represent the bonds present:
We now need to work out how many of each bond type we have broken.
8xC-H
2xC-C
5xO=O
And then how many bonds ha…
