(c) 0.1M BaCl₂ (d) 0.1M K₂SO₄

1A
2B
3C
4D

3.

Equimolar solutions in the same solvent have

1Same boiling point but different freezing point
2Same freezing point but different boiling point
3Same boiling and same freezing points
4Different boiling and different freezing points

4.

The relative lowering of the vapour pressure is equal to the
ratio between the number of

1Solute moleules and solvent molecules
2Solute molecules and the total molecules in the solution
3Solvent molecules and the total molecules in the solution
4Solvent molecules and the total number of ions of the solute

The relative lowering of the vapour pressure of dilute
solution is equal to the mole fraction of the solute
molecule present in the solution.

5.
