You perform a combustion analysis on a 255 mg sample of a substance that contains only C, H, and O, and you find that 561 mg CO2 is produced, along with 306 mg of H20. (Combustion means that you react the molecule with 02. The products of a combustion reaction are only carbon dioxide and water.) If the substance contains only C, H, and O, what is the empirical formula? If the molar mass of the compound is 180 g/mol, what is the molecular formula of the compound?
