Solution :
When non volatile solute is added to solvent, vapor pressure gets lowered.
Relative lowering in vapor pressure is given :
=
of solute
= vapor pressure of pure solvent
P = vapor pressure of solution
= mole fraction of solute
=
=
Number of moles
1. For 10 g of
Ions = 2
It will affect colligative property.
Relative lowering in vapor pressure will be :
2. For 20 g sucrose
Sucrose is non electrolyte, i = 1
3. For 20 g of glucose.
Glucose is a non electrolyte, i = 1
is same in all three solutions.
Hence, lowering in vapor pressure is maximum in and minimum is Sucrose.
Vapor pressure from lowest to highest.
10 g of < 20 g of glucose < 20 g of sucrose
