The vapour pressure of water depends upon :

Vapour pressure of a liquid depends upon its

The vapour pressure of water at room temperature is 30 mm of Hg. If the mole fraction of the water is 0.9, the vapour pressure of the solution will be :

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