How can one determine the molar mass of a substance using the freezing point depression method?

To determine the molar mass of a substance using the freezing point depression method, you can measure the decrease in freezing point when a solute is added to a solvent. By knowing the amount of solute added and the decrease in freezing point, you can calculate the molar mass of the solute using the formula: molar mass (mass of solute / moles of solute) (freezing point depression / change in freezing point).
