Q.

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

  1. A

    2A

  2. B

    3A

  3. C

    A

  4. D

    4A

Solution

(Since density of solutions are not given therefore assuming molality to be equal to molarity and given % as % W/V)
