Question

A solution is obtained by dissolving 12 gm of
urea (mol. wt. 60) in a litre of water. Another
solution is obtained by dissolving 68.4 gm of
cane sugar (mol. wt. 342) in a litre of water at the
same temperature. The lowering of vapour
pressure in the first solution is
(a) same as that of 2nd solution
(b) nearly one-fifth of the 2nd solution
(c) double that of 2nd solution
(d) nearly five times that of 2nd solution

Answer 1

Answer:

a. Is the correct answer

As you can see in both case moles of solute is same so that relative lowering in vapor pressure will be same .
