Which fuel would produce the largest mass of CO2 when 10kg of the fuel undergo complete combustion?
A biodiesel, C17H34O2
B ethanol, C2H6O
C octane, C8H18
D propane, C3H8
I have written balanced equations for each fuel's reaction with oxygen and it leads me to believe that A is the right answer. It this correct?

You must determine the number of moles of each fuel in 10kg, by dividing by the relative mass.
Then multiply by the number of carbon atoms in the molecule.
