Calculate the change in boiling or freezing temperature using one the following formulas: ΔTf = Kf * m or ΔTb = Kb* m.
Add the value obtained for ΔTb to the standard boiling point of the solvent (ex. 100 C for water) or subtract the value obtained for ΔTf from the standard freezing point of the solvent (ex. 0 C for water).
