The relative lowering of vapour pressure of a solution is proportional to the

The vapour pressure of an aqueous solution of glucose at 100 °C is 710 mm Hg. Hence the molality of the solution is

Relative vapour pressure lowering depends only on

A solution having mole fraction of a solute equal to 0.05 has vapour pressure $20\times {10}^{3}N{m}^{-2}\mathrm{.}20\; \backslash times\; 10\; ^3\; \backslash ,Nm\; ^\{-2\}.$ Hence the vapour pressure of a pure solvent is :

The addition of the nonvolatile solute into the pure solvent …………

A solution having the highest vapour pressure is

Molal elevation constant is elevation in boiling point produced by

The determination of molar mass from elevation in boiling point is called

Which of the following aqueous solutions will have minimum elevation in boiling point ?

Which of the following solutions shows maximum depression in freezing point ?
