A fuel consisting of only carbon and hydrogen is completely combusted with pure oxygen at a rate that is 15% in excess of that required for complete combustion. The exhaust gases on a dry mol % basis are: 75% CO2, 4% CO and 21% O2. Calculate the molar composition of the fuel (eg. C35.7H62.5). Hint: just because water vapour is not included in the exhaust gas analysis (because it is on a dry basis) doesnt mean there is no water
