Mole Fraction of Solute given Vapour Pressure Solution

STEP 0: Pre-Calculation Summary

Formula Used

Mole Fraction of Solute = (Vapour Pressure of Pure Solvent-Vapour Pressure of Solvent in Solution)/Vapour Pressure of Pure Solvent
x_solute = (p_o-p)/p_o
This formula uses 3 Variables

Variables Used

Mole Fraction of Solute - Mole Fraction of Solute is the ration of the number of moles of the solute to the total number of moles of the solute and solvent.
Vapour Pressure of Pure Solvent - (Measured in Pascal) - The Vapour Pressure of Pure Solvent is the vapour pressure of solvent prior to addition of solute.
Vapour Pressure of Solvent in Solution - (Measured in Pascal) - The Vapour Pressure of Solvent in Solution is the vapour pressure of solvent post addition of solute.

STEP 1: Convert Input(s) to Base Unit

Vapour Pressure of Pure Solvent: 2000 Pascal --> 2000 Pascal No Conversion Required
Vapour Pressure of Solvent in Solution: 1895.86 Pascal --> 1895.86 Pascal No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

x_solute = (p_o-p)/p_o --> (2000-1895.86)/2000

Evaluating ... ...

x_solute = 0.05207

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.
