An unidentified covalent molecular compound contains only carbon, hydrogen, and oxygen. When 9.40 mg of this compound is burned, 24.11 mg of CO2 and 2.82 mg of H2O are produced.
The freezing point of camphor is lowered by 34.4°C when 2.066 g of the compound is dissolved in 10.00 g of camphor (Kf = 40.0°C kg/mol).

What is the molecular formula of the unidentified compound?

In typing this formula use the format of carbon first, hydrogen second, and oxygen last (e.g. C4H9O3).
