5. If 22 gm of benzene is dissolved in 122 gm of carbontetrachloride, calculate mass percentage of benzene.
Total mass of the solution = 22 + 122 = 14 gmMass % of benzene = (22 x 100)/144 = 15.28%
Mass % of carbontetrachloride = (122 x 100)/144 = 84.72%
5. or. Define colligative property.
A colligative property is the property of a dilute solution which dependent on the number of solute particles present in the solution and not on the chemical nature of the solute paerticles. It is of four types-1. Relative lowering of vapour pressure
2. Depression in freezing point
3. Elevation in boiling point
4. Osmotic pressure
