An unidentified covalent molecular compound contains merely carbon, hydrogen and oxygen. While 8.80 mg of this compound is burned 18.81 mg of CO2 and 2.20 mg of H2O are produced. The freezing point of camphor is lowered by 26.4°C while 2.663 g of the compound is dissolved in 14.00 g of camphor (Kf = 40.0 K kg/mol.) Explain what is the molecular formula of the unidentified compound?
