A fuel oil is composed of C10H22 and C12H26 in an unknown ratio (no other components are in the fuel oil).

A fuel oil is composed of C10H22 and C12H26 in an unknown ratio (no other components are in the fuel oil). When the fuel oil is burned with 20% excess air the exhaust is tested and the ratio of water to CO2 is found to be 1.088. Please note that the reaction proceeds to 100% completion (no unburned oil or CO in product stream). Determine the composition of the fuel oil.
