An unknown compound contains only carbon, hydrogen, and oxygen. Combustion analysis of the compound gives mass percents of 31.57 % C and 5.30 % H. The molar mass is determined by measuring the freezingpoint depression of an aqueous solution. A freezing point of -5.20^∘ C is recorded for a solution made by dissolving 10.56 g of the compound in 25.0 g of water. Determine the empirical formula, molar mass, and molecular formula of the compound. Assume that the compound is a nonelectrolyte. | Numera
