A`5%` solution of cane sugar (molar mass =`342`)is isotonic with `1%`of a solution of an known solute.The molar mass of unknown solute in g/mol is

A

136.2

B

171.2

C

68.4

D

34.2

Text Solution

Verified by Experts

The correct Answer is:
C
Isotonic solutions have equal molar concentrations. Hence,
`(5//342)/100 xx 1000 = (1//M)/100 xx 1000`
or `5/342 =1/M` or `M=68.4`
