Two 5 molal solution are prepared by dissoliving a non elecrtroyte non volatile solute separately in the solvents X nad Y The molecular weights of the solvents are `M_(x) and M_(y)` respecitvely where
`M_(x)=3/4 M_(y)` The relative lowering of vapour pressure of the solution in is 'm' times that of the solution in y given that the number of moles of solute is very small in comparison to that of solvent the value of ''m'' is :

Two 5 molal solutions are prepared by dissolving a non-electroylete, non -volatile solute separately in the solvents X and Y. The molecular weights of the solvents are M_(x) and M_(Y) , respectively where M_(X)=4/3M_(Y) . The relative lowering of vapour pressure of the solution in X is "m" times that of the solution in Y. Given that the number of moles of solute is very small in comparision to that of solvent, the value of "m" is :

The relative lowering of vapour pressure of a solution on the addition of non-volatile solute

The relative lowering of vapour pressure of an aqueous solution containing non - volatile solute is 0.0125 . The molality of the solution is

The relative lowering of vapour pressure of an aqueous solution containing a non-volatile solute, is 0.0125. The molality of the solution is
