Molal depression constant is calculated ...

Molal depression constant is calculated from the enthalpy of fusion `(DeltaH_(f))` and b.pt. of solvent using the relation.

A

`K_(f)=(M_(1)RT_(0)^(2))/(1000DeltaH_(f))`

B

`K_(f)=(1000RT_(0)^(2))/(M_(1)DeltaH_(f))`

C

`K_(f)=(1000M_(1)T_(0)^(2))/(RDeltaH_(f))`

D

`K_(f)=(DeltaH_(f))/(1000M_(1)T_(0)^(2))`

Text Solution

Verified by Experts

The correct Answer is:
