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. freewebmaps

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: Solved Experiment 14 Report Sheet Molar Mass of

The lab report (often listed as Experiment 14 in chemistry courses) is a common laboratory exercise used to determine the molar mass of an unknown substance through freezing point depression , a colligative property. Key Components of the Report Key Components of the Report Usually, cyclohexane is

Usually, cyclohexane is used as the solvent. Its pure freezing point is recorded from a cooling curve.
