Question

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 remaining mass percent is oxygen. A
solution of 10.56 g of the compound in 25.0 g of water has a freezing point of -5.20oC. Determine the
empirical formula, the molar mass, and the molecular formula of the compound. Assume that the
compound is a nonelectrolyte. (Water has Kf = 1.86oC/m)
