1. Determine the freezing point lowering Tf for a known molality solution of an ionic solute such as ammonium chloride. 2. Determine the freezing point lowering Tf for a known molality solution of a molecular solute. Assume that the solute would not dissociate in this solvent. 3. Determine the freezing point lowering Tf for a series of different molality solutions of an ionic solute and determine Kf by plotting Tf versus molality. The value of Kf can be determined from the slope of this line. 4. Determine the freezing point lowering Tf for a series of different molality solutions of a molecular solute and determine Kf by plotting Tf versus molality. The value of Kf can be determined
