## Mole Fraction of solute in terms of Vapour Pressure Solution

STEP 0: Pre-Calculation Summary
Formula Used
mole_fraction_solute = (Vapour Pressure of Pure Solvent-Vapour Pressure of Solvent in Solution)/Vapour Pressure of Pure Solvent
x1 = (PoA-PA)/PoA
This formula uses 2 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)
STEP 1: Convert Input(s) to Base Unit
Vapour Pressure of Pure Solvent: 20000 Pascal --> 20000 Pascal No Conversion Required
Vapour Pressure of Solvent in Solution: 15000 Pascal --> 15000 Pascal No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
x1 = (PoA-PA)/PoA --> (20000-15000)/20000
Evaluating ... ...
x1 = 0.25
STEP 3: Convert Result to Output's Unit
0.25 --> No Conversion Required
0.25 <-- Mole Fraction Of Solute

### Mole Fraction of solute in terms of Vapour Pressure Formula

mole_fraction_solute = (Vapour Pressure of Pure Solvent-Vapour Pressure of Solvent in Solution)/Vapour Pressure of Pure Solvent
x1 = (PoA-PA)/PoA

## 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.
