Molecular Mass of Solvent given Relative Lowering of Vapour Pressure Solution

STEP 0: Pre-Calculation Summary

Formula Used

Molecular Mass Solvent = ((Vapour Pressure of Pure Solvent-Vapour Pressure of Solvent in Solution)*1000)/(Molality*Vapour Pressure of Pure Solvent)
M = ((p_o-p)*1000)/(m*p_o)
This formula uses 4 Variables

Variables Used

Molecular Mass Solvent - (Measured in Kilogram) - The Molecular Mass Solvent is sum of the atomic masses of all atoms in a molecule, based on a scale in which the atomic masses.
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.
Molality - (Measured in Mole per Kilogram) - Molality is defined as the total number of moles of solute per kilograms of solvent present in the solution.

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
Molality: 1.79 Mole per Kilogram --> 1.79 Mole per Kilogram No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

M = ((p_o-p)*1000)/(m*p_o) --> ((2000-1895.86)*1000)/(1.79*2000)

Evaluating ... ...

M = 29.0893854748604

STEP 3: Convert Result to Output's Unit

29.0893854748604 Kilogram -->29089.3854748604 Gram (Check conversion here)

FINAL ANSWER

29089.3854748604 ≈ 29089.39 Gram <-- Molecular Mass Solvent

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.
