Expert Solution
Step 1

When solute is added to water, the freezing point of resulting solution is decreased known as depression in freezing point (ΔTf).

The mathematical expression for the lowering or depression in freezing point is given as :

ΔTf = i x Kf x m

where,

i = Vant Hoff factor

Kf = molar depression constant of solvent  (water)

m = molality
