Does any one know the exact Kilojoules to carbon dioxide ratio for these fuels?

Question

Methanol

Ethanol

Gasoline

Methane

I've been checking with my peers but we all seem to have different ratios. So i dont know who is right. and whos wrong.

Carbon Dioxide Moles by the way, thx.

Answer 1

You can figure out the moles of CO2 by balancing the equation fuel + O2 -> CO2 + H2O.

Then just do a google search for "energy content fuels" or alternatively figure it out from the heat of formation for the CO2, H2O, and fuel. I'd go with google :)
