n moles of a non volatile solute are dissolved in wg of water. If `K_(f)` is the molal depression constant of water, the freezing point of the solution will be

A

`(1000 K_(f)n)/(w)`

B

`-(1000K_(f)n)/(w)`

C

`(1000K_(f)w)/(n)`

D

`-(1000K_(f)w)/(n)`

Text Solution

Verified by Experts

The correct Answer is:
A
We know that `DeltaT_(f) = (k_(f)xxw xx 1000)/(MxxW)` ltbr. Or `T^(-)-T =(k_(f)xxwxx1000)/(MxxW)`
