A 5% solution of cane sugar (molecular weight =342) is isotonic with 1% solution of substance X. The molecular weight of Xis

A

171.2

B

68.4

C

34.2

D

136.2

Text Solution

Verified by Experts

The correct Answer is:
B
For non-electrolytic solutions, if isotomic `C_(1)=C_(2) =(5 xx 1000)/(342 xx 100)=(1 xx 1000)/(Mw_2 xx 100)`
`Mw_(2)=68.4`
