Mw(N)= Normal molecular mass of solute ...

`Mw_(N)`= Normal molecular mass of solute
`Mw_(2)`= Observed molecular mass of solute from colligative property measurement

Text Solution

Verified by Experts

The correct Answer is:
`A-r,s B-r, C-p, D-q`
(A) 0.1M `CH_(3)COOH` in benzene `rArr i lt (M w_(2) gt Mw_(N))`
(B) 0.1 M urea in water `rArr i= 1 (Mw_(2)= Mw_(N))`
(c ) `0.05M BaCl_(2)` in water `rArr i=3` (assuming `alpha=1`) `(Mw_(2)= (Mw_(N))/(3))`
(D) `0.1M CH_(3)COOH` in water `rArr i gt 1 (Mw_(0) lt Mw_(n))`
