Freezing point of a 4% aqueous solutio...

Freezing point of a 4% aqueous solution of X is equal to freezing point of 12% aqueous is reaction of Y .if molecular weight of X is A then molecular weight of Y is :

A

`4A `

B

`2A`

C

`3A`

D

`A`

Text Solution

Verified by Experts

The correct Answer is:
C
`(DeltaT_f)_X=(DeltaT_f)_Y`
`k_fm_X=k_fm_Y`
`(4xx1000)/(Axx96)=(12xx1000)/(Mxx88)implies M = 3.27A ~~3A`
