5% sucrose solution is isotonic with 1% 'X' solution. What will be the molecular weight of 'X' ?

A

343 gram/mole

B

180 gram/mole

C

68.4 gram/mole

D

171 gram/mole

Text Solution

Verified by Experts

The correct Answer is:
C
For the 5 % solution `(5)/(M_(1))` and 1% solution `= (1)/(M_(2))`
`therefore (5)/(342)=(1)/(M_(2))`
`therefore M_(2)=68.4` gram/mole.
