Assertion: If solutions of sugar, urea, ...

Assertion: If solutions of sugar, urea, glucose in water are prepared by dissolving one mole of each of the solute in 1000g of water, they will show identical lowering of vapour pressure.
Reason: Colligative properties depend entirely on the number of particles of solute present in solution and not on the nature of solute.
