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.
Usually, cyclohexane is used as the solvent. Its pure freezing point is recorded from a cooling curve. freewebmaps
The final result is found by dividing the mass of the solute used by the number of moles calculated. Typical Lab Report Values freewebmaps
