delta Tf = i*Kf*m The expresssion for the freezing point depression of a solution relative to that of the pure solute is shown above.

delta Tf = i*Kf*mThe expresssion for the freezing point depression of a solution relative to that of the pure solute is shown above. From solutions of known concentrations of p-dichlorobenzene in cyclohexane, you determine Kf, the freezing point depression constant of cyclohexane. What assumption is necessary in order to do these calculations?
