ΔTf=Tf,solvent−Tf,solutioncap delta cap T sub f equals cap T sub f comma solvent end-sub minus cap T sub f comma solution end-sub Using the formula Kfcap K sub f for cyclohexane is approximately ), you find the molality and then the moles of solute.
A solid lab report for this experiment typically includes the following data sections and calculations:
The freezing point is measured again after a known mass of an unknown solid solute is added to the solvent. Calculation of ΔTfcap delta cap T sub f : This is the change in freezing point, calculated as:
