Question
**Menthol and Its Molar Mass Calculation** Menthol is a crystalline substance characterized by its peppermint taste and odor. **Problem Statement:** When 1.18 grams of menthol is dissolved in 25.0 grams of cyclohexane, the freezing point of the solution is lowered by 6.31 °C. You will need to refer to the Colligative Constants table to find the freezing point and \( K_f \) constant for cyclohexane. **Objective:** Calculate the molar mass of menthol. **Molar Mass Calculation:** - There is a box provided to input the molar mass value, labeled "molar mass: ___ g/mol". **Note:** Ensure to look up the necessary values from the Colligative Constants table to proceed with the calculation. **End of Exercise** The problem encourages students to apply concepts of colligative properties to determine the molar mass of a solute. No diagrams or graphs are present in the image.
