Open Question: Molecular Formula from Elemental Analysis and Molecular Mass Determination?

An unidentified covalent molecular compound contains only carbon, hydrogen, and oxygen. When 8.20 mg of this compound is burned, 17.53 mg of CO2 and 2.05 mg of H2O are produced.
The freezing point of camphor is lowered by 42.4°C when 4.735 g of the compound is dissolved in 15.50 g of camphor (Kf = 40.0°C kg/mol).

What is the molecular formula of the unidentified compound?
