Combustion of a hydrocarbon in a limited supply of air produces CO in addition to CO2 and H2O. When 1.80 g of a particular hydrocarbon was burned in air, 1.74 g CO, 2.73 g CO2, and 2.80 g H2O were produced. What is the empirical formula of the hydrocarbon? Calculate the mass of oxygen used in the reaction. Calculate the total mass of oxygen that would have been required for complete combustion.
