Combustion of a hydrocarbon in a limited supply of air produces CO in addition to CO, and H,O. When 2.84 g of a particular hydrocarbon was burned in air, 2.74 g CO, 4.30 g CO₂, and 4.40 g H2O were produced. What is the empirical formula of the hydrocarbon? empirical formula: C₂H Calculate the mass of oxygen used in the reaction. mass: 8.59 Calculate the total mass of oxygen that would have been required for complete combustion. mass: 9.33 g 0 g
