A standard internal combustion engine burns liquid octane (C8H18C_8H_{18}C8H18) as a fuel. Under restricted air flow conditions, the fuel undergoes incomplete combustion such that the molar ratio of carbon monoxide (COCOCO) to carbon dioxide (CO2CO_2CO2) in the dry exhaust gas is 1:31:31:3, with no unburnt carbon (soot) remaining.
What is the volume of oxygen gas, measured at room temperature and pressure (RTP, where the molar volume of gas is 24 dm3 mol-1), required for the incomplete combustion of exactly 1.00 mol of octane?
