Question

Calculate freezing point of sugar solution having concentration 0.1 molal
(Given Kf=1.86 K kg/mol)

Answer 1

Answer:

The freezing point depression ∆T = KF·m where KF is the molal freezing point depression constant and m is the molality of the solute. Rearrangement gives: mol solute = (m) x (kg solvent) where kg of solvent is the mass of the solvent (lauric acid) in the mixture. This gives the moles of the solute.
