Question

12 g of urea and 68.4 g sucrose each is dissolved if 1 litre of water. The relative
lowering in vapour pressure of urea solution is
(a) greater than sucrose solution
(b) less than sucrose solution
(c) double that of sucrose solution
(d) equal to that of sucrose solution​

Answer 1

explanation Solution:

urea

sucrose

As mole fraction of solute is same hence, lowering of vapour pressure is same.
