Question
Dry air was passed successively through a solution of 5 g of a solute in 180 g of water and then through pure water. The loss in the weight of solution was 2.50 g and that of pure sovent 0.04 g. The molecular weight of the solute is
Options
A.31.25
B.3.125
C.312.5
D.None
Solution
Po - Ps ∝ loss in weight of water chamber and PS ∝ loss in weight of solution chamber.
or
∴ Mw2 = 31.25
or
∴ Mw2 = 31.25
