Approx. #0.03*L_(CO_2)*mJ^-1#

Explanation:

The energy released by combustion of one mole of ethane is #-1560*kJ#...agreed?

And production of this energy gives rise to TWO moles of carbon dioxide....the which at SLC has a volume of #24.5*L#...you will have to check this. Definitions vary across the syllabuses (syllabi?, syllabub?)

Now combustion of one mole of ethanol clearly gives rise to 2 moles of carbon dioxide....and so we take the quotient...

#"Volume of carbon dioxide in cubic metres"/"Energy released in megajoules"#

i.e. #1*m^3-=1000*L#, a #m^3# is a huge volume.

#=(2xx24.5*L*10^-3*m^3*L^-1)/(1560*kJxx10^-3*mJ)=#

#0.0314*L*mJ^-1#
