This formula uses 3 Variables
Variables Used
Vapour Pressure of Pure Solvent - The Vapour Pressure of Pure Solvent is the vapour pressure of solvent prior to addition of solute. (Measured in Pascal)
Vapour Pressure of Solvent in Solution - The Vapour Pressure of Solvent in Solution is the vapour pressure of solvent post addition of solute. (Measured in Pascal)
Molality - Molality is defined as the total number of moles of solute per kilograms of solvent present in the solution. (Measured in Mole per Kilogram)

What causes the Relative Lowering Of Vapour Pressure?

This lowering in vapour pressure is due to the fact that after the solute was added to the pure liquid (solvent), the liquid surface now had molecules of both, the pure liquid and the solute. The number of solvent molecules escaping into vapour phase gets reduced and as a result the pressure exerted by the vapour phase is also reduced. This is known as relative lowering of vapour pressure. This decrease in vapour pressure depends on the amount of non-volatile solute added in the solution irrespective of its nature and hence it is one of the colligative properties.
