    QUESTION 25 The molar mass of a compound can be determined by the freezing point depression method. The solution must be relatively dilute and you must know the molal freezing point depression constant of the solvent, Kf: Which statement regarding Kris true? Kf should be small so that the solvent will not sublimate, Kf will change depending on what solute is dissolved in the solvent. Kfshould be negative so the freezing point of the solution will decrease. Kfshould be large...
