Given that `DeltaT_(f)` is the depression in freezing point of the solvent in a solution of a non-volatile solute of molarity `m`,the quantity `underset(m rarr0)(Lt) (DeltaT_(f)//m)` is equal to ……………. .

Options

A. Zero
B. One
C. Three
D. None of the above

Answer

D

Explanation

`DeltaT_(f)=mxxK_(f)`
`(DeltaT_(f))/(m)=K_(f)`
`underset(mrarr0)(lim)((DeltaT_(f))/(m))` will remain a constant value as `K_(f)` is constant for a solvent.
