Molal depression constant is calculated ...

Molal depression constant is calculated from the enthalpy of fusion `(DeltaH_(f))` and boiling point of solvent using the relation

Text Solution

Verified by Experts

Molar depression constant `K_(f)` is related to the enthalpy of fusion `DeltaH_(f)` as :
`K_(f) = (RT_(f)^(2)M)/(Delta H_(f) xx 1000)`
where M is the molar mass and `T_(f)` is the freezing point.
