The vapour pressure of solvent is 20 torr, while that of its dilute solution is 17 torr , the mole-fraction of the solvent is

The vapour pressure of a solvent is 60 torr while that of its dilute solution is 52 torr. The mole fraction of the solvent is :

The vapour pressure of a solvent decreases by 10 mm of Hg when a non-volatile solute is added to it. The mole fraction of the solute in solution is equal to 0.2. What should be the mole fraction of solvent if the decrease in vapour pressure is to be 20 mm Hg?

If P^(@) the vapour pressure of a pure solvent and P is the vapour pressure of the solution prepared by dissolving a non volatile solute in it. The mole fraction of the solvent X_(A) is given by:

If P^(@) the vapour pressure of a pure solvent and P is the vapour pressure of the solution prepared by dissolving a non volatile solute in it. The mole fraction of the solvent X_(A) is given by:

If P^(@) the vapour pressure of a pure solvent and P is the vapour pressure of the solution prepared by dissolving a non volatile solute in it. The mole fraction of the solvent X_(A) is given by:

The vapour pressure of a liquid decreases by 10 torr when a non-volatile solute is dissolved. The mole fraction of the solute in solution is 0.1. What would be the mole fraction of the liquid if the decrease in vapour pressure is 20 torr, the same solute being dissolved?

The vapour pressure of a liquid decreases by 10 torr when a non-volatile solute is dissolved. The mole fraction of the solute in solution is 0.1. What would be the mole fraction of the liquid if the decrease in vapour pressure is 20 torr, the same solute being dissolved?

If P_(@) and P_(S) are the vapour pressure of the solvent and its solution respectively and x_(1) and x_(2) are the mole fraction of the solvent and solute respectively, then
