Question
12g of urea is dissolved in 1 litre of water and 68.4g of sucrose is dissolved in 1line of water. The lowering of vapour pressure of first case is
Options
A.equal to second
B.greater than second
C.less than second
D.double that of second
Solution
Moles of urea = 
= 0.2
Moles of sucrise =
= 0.2
Both are non electrolyte hence lowering of V.P will be same.
= 0.2Moles of sucrise =
= 0.2 Both are non electrolyte hence lowering of V.P will be same.
