If a non-volatile solute is dissolved in a volatile solvent relative lowering of vapour pressure is equal to

The relative lowering in vapour pressure is:

For a non-volatile solute

What is relative lowering of vapour pressure ?

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

When non-volatile solute is added to a pure solvent, the:

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

Calculate relative lowering of vapour pressure of 0.161 molal aqueous solution

The mole fraction of the solvent in the solution of a non-volatile solute is 0.980. The relative lowering of vapour pressure is :

(a) A solution is prepared by dissolving 10g of non-volatile solute in 180g of H_(2)O . If the relative lowering of vapour pressure is 0.005 , find the molar mass of the solute. (b) How many grams of sucrose (C_(12)H_(22)O_(11)) must be dissolved in 90g of water to produce a solution over which the relative humidity is 80% ? Assume the solution is ideal.

When 25 g of a non-volatile solute is dissolved in 100 g of water, the vapour pressure is lowered by 2.25xx10^(-1)mm of Hg. What is the molecular weight of the solute? [ P^(@)= 17.73 mm of Hg]
