The molecular mass of a solute cannot be calculated by one of the following relations

A

`M_(B) = (K_(b) xx 1000 xx w_(B))/(Delta T_(b) xx w_(A))`

B

`M_(B) =(w_(B) xx RT)/(piV)`

C

`M_(B) = (p_(0) xx w_(B) xx M_(A))/((p_(0)-p) xx w_(A))`

D

`M_(B) = (Delta T_(b))/(K_(b)) xx 1000 (w_(B))/(w_(A))`

Text Solution

Verified by Experts

The correct Answer is:
A
The correct expression for determination of molecular mass is
`M_(B) = (K_(b) xx w_(B) xx 1000)/(DeltaT_(b) xx w_(A))`
