A solution containing`8,6` urea in one litre was found to be isotonic with a `5%`(wt./vot.)solution of an organic non-volatile solute. The molecular weight of latter is:

A

`348.9`

B

`34.89`

C

`3489`

D

`861.2`

Text Solution

Verified by Experts

The correct Answer is:
A
For two non-electrolytic solutions if isotonic`C_(1)=C_(2)`
`:.(8.6)/(60xx1)=(5xx1000)/(mxx100):.m=348.9`
