Lowering of vapour pressure of solution

What is lowering of vapour pressure of a solution.

Vapour pressure of a solution is

The lowering of vapour pressure of a solvent by the addition of a non- volatile solute to . It , is directly proportional to _______.

How will you lower the vapour pressure of a solution?

A solutions is prepared by dissolving 394 g of a nonvolatile solute in 622 g of water. The vapour pressure of solution is found to be 30.74 mm Hg at 30^@C . If vapour pressure of water at 30^@C is 31.8mm Hg, what is the molar mass of solute?

According to the Raoult’s law, 'the relative lowering of vapour pressure is equal to the

5 cm^(3) of acetone is added to 100 cm^(3) of water . Then the vapour pressure of the vapour pressure of the solution _______.
