What is relative lowering of vapour pressure ?

The relative lowering in vapour pressure is:

Calculate the relative lowering of vapour pressure of a 10% aqeous caustic soda solution.

Unit of lowering of vapour pressure 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

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

The vapour pressure of a pure liquid at 25^(@)C is 100 mm Hg. Calculate the relative lowering of vapour pressure if the mole fraction of solvent in solution is 0.8.

The relative lowering of vapour pressure of an aqueous solution of a non-volatile solute of molecular weight 60 (which neither dissociates nor associates in the solution) is 0.018. If K_(f) of water is 1.86^(@)Cm^(-1) the depression in freezing point will be :

12g of a nonvolatile solute dissolved in 108g of water produces the relative lowering of vapour pressure of 0.1 . The molecular mass of the solute is

According to Raoult's law the relative lowering of vapour pressure for a solution is equal to
