Menthol is a crystalline substance with a peppermint taste and odor. When 0.523 g of menthol is dissolved in 25.0 g of cyclohexane, the freezing point of the solution is lowered by 2.79 ∘C. Look up the freezing point and ?f constant for cyclohexane in the Colligative Constants table. Calculate the molar mass of menthol.
