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:
Reports available on academic platforms like Studocu and Chegg often show: ~8-10 grams. Kfcap K sub f for Cyclohexane: Solute Mass: Roughly 0.2 to 0.5 grams per trial. freewebmaps
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 The freezing point is measured again after a

The final result is found by dividing the mass of the solute used by the number of moles calculated. Typical Lab Report Values
