When 12.4 g of an organic compound known to be 57.15% C, 4.8% H, and 38.06% O by mass is dissolved in 937.9 g of cyclohexane, the freezing point is 4.41 °C. The normal freezing point of cyclohexane is 6.59 °C. What is the molecular formula for the organic compound? Assume that the organic compound is a molecular solid and does not ionize in water. Kf values for various solvents are given in the colligative constants table.
