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

3A

B

A

C

4A

D

2A

Text Solution

Verified by Experts

`(DeltaT_(f))_(x)=(DeltaT_(f))_(Y)`
`impliesK_(f)xxm_(x)=K_(f)xxm_(Y)" "implies(4xx1000)/(Axx96)=(12xx1000)/(Mxx88)" "M=(96xxAxx12)/(8xx4)=3.27A~~3A`
