Moles of Solute in Dilute Solution given Relative Lowering of Vapour Pressure Solution

STEP 0: Pre-Calculation Summary

Formula Used

Number of Moles of Solute = ((Vapour Pressure of Pure Solvent-Vapour Pressure of Solvent in Solution)*Number of Moles of Solvent)/Vapour Pressure of Pure Solvent
n = ((p_o-p)*N)/p_o
This formula uses 4 Variables

Variables Used

Number of Moles of Solute - (Measured in Mole) - The number of Moles of Solute is the total number of representative particles present in the solute.
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.
Number of Moles of Solvent - (Measured in Mole) - Number of Moles of Solvent is the total number of representative particles present in the solvent.

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
Number of Moles of Solvent: 10 Mole --> 10 Mole No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

n = ((p_o-p)*N)/p_o --> ((2000-1895.86)*10)/2000

Evaluating ... ...

n = 0.5207

STEP 3: Convert Result to Output's Unit

0.5207 Mole --> No Conversion Required

FINAL ANSWER

0.5207 Mole <-- Number of Moles of Solute

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.
