A current of dry air is passed through the above apparatus containing two sets of bulbs . One set of bulbs is filled with the solution and second with the solvent . Finally that is attched with a U-tube containing CaCl_(2) , which is very efficient in absorbing the water vapour. Passing of dry air through all these three causes some change in weight. Dry air was passed through solution of 5g of solute in 80g of water and the passed thriugh pure water . The loss in weight of solution was 2.5g and that of pure water was 0.04g . The molecular mass of solute is
