Camphor is often used in molecular mass ...

Camphor is often used in molecular mass determination because

A

it is reading available

B

it has a very high cryoscopic constant

C

it is volatile

D

it is a solvent for organic substances

Text Solution

Verified by Experts

The correct Answer is:
2
We have
`DeltaT_(f)=iK_(f)m`
For a given concentration of a solution, the magnitude of `DeltaT_(f)` is directly related to the value of `K_(f)`. Among the available solvents, camphor has the highest value of `K_(f)(40 K kg mol^(-1))` and thus gives the maximum depression of freezing point for a given amount of solute.
