Question

the relative lowering of vapour pressure is equal to the mole fraction of​

Answer 1

relative lowering of vapor pressure and the concentration of the solute in a solution. This is now referred to as the Raoult's Law. As per this law, the relative lowering of the vapor pressure of a dilute solution is equal to the mole fraction of the solute present in dilute solution.

Answer 2

Solutions. Prove that the relative lowering of vapour pressure is equal to the mole fraction of non-volatile solute in the solution. Answer: Raoult established that the lowering of vapour pressure depends only on the concentration of the solute particles and it is independent of their identity.
