If a `6.84% (weight//volume)` solution of cane sugar (molecular weight=342) is isotonic with `1.52%(weight//volume)`solution of thiocarbamide, then the molecular weight of thiocarbamide is

A

152

B

760

C

60

D

180

Text Solution

Verified by Experts

The correct Answer is:
B
For two non-electrolyte solutions, if isotonic `C_(1)=C_(2)`.
`:. (6.84 xx 100)/(342 xx 100) =(1.52 xx 1000)/(Mw_(2) xx 100) rArr Mw_(2) =760`
