The normal freezing point of nitrobenzen...

The normal freezing point of nitrobenzene `(C_(6)H_(5)NO_(2))` is `278.82K`. `A 0.25` molal solution of a certain solute in nitrobenzene causes a freezing point depression of `2` degrees. Calculate the value of `K_(f)` for nitrobenzene.

Text Solution

Verified by Experts

`DeltaT_(f)=K_(f)m`
`K_(f)=(DeltaT_(f))/(m)=(2)/(0.25)=8" K kg mole"^(-1)`
