Question

Solution a obtained by dissolving 1g of urea in 100gm of water and solution b is obtained by dissolving 1gm of glucose in 100gm of water which solution will have higher boiling point

Answer 1

The elevation in boiling point is directly proportional to the molality of the solute added as 'i' is one for both. As the mass of solvent for both the solutions is the same and therefore

the increase in boiling point depends on the moles of each solute present.

Moles of urea = 1/60 = 0.017moles and mole of glucose = 1/180 = 0.0056mol

The solution of urea will show a hiher increase in boiling point.

hope its right
