The vapour pressure of water is 12.3 kPa at 300 K. Calculate vapour pressure of 1 molal solution of a non-volatile solute in it.

What happens to the vapour pressure of a liquid when a non-volatile solute is added to it

Why is the vapour pressure of a solvent lowered on the addition of non-volatile solute into it ?

The vapour pressure of water at 293K is 0.0231 bar and the vapour pressure of a solution of 108.24 g of a compound in 1000 g of water at the same temperature is 0.0228 bar. Calculate the molar mass of the solute.

How will you calculate the molecular mass of a solute with the help of relative lowering in vapour pressure of a solution of a non volatile solute?

(a) Define vapour pressure (b) Explain why vapour pressure of a solvent lowered by the addition of non-volatile solute ?

Vapour pressure of water at 293 K is 17.535 mm Hg. Calculate the vapour pressure of water at 293 K when 25 g of glucose is dissolved in 450 g of water.

100 g of liquid A (molar mass 140 g mol^(-1) was dissolved in 1000 g of liquid B (molar mass 180 g mol^(-1)) . The vapour pressure of pure liquid B was found to be 500 torr. Calculate the vapour pressure of pure liquid A and its vapour pressure in the solution if the total vapour pressure of the solution is 475 Torr.

How can you justify the observtation that the vapour pressure of the solution of a non-voltile solute in a given solvent is lower than that of the pure solvent. Also the laws concerning this observations.
