Question

solutions all problem and answer of relative lowering in vapour pressure​

Answer 1

Answer:

Explanation:

Since the solute molecules are non-volatile, the vapour above the solution consists of only solvent (pure liquid) molecules. After adding the solute, the vapour pressure of the solution is found to be lower than that of the pure liquid at a given temperature. ... This is known as relative lowering of vapour pressurerelative 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.
