A 0.6% solution of urea ( molar mass =60) would be isotonic with

Answer»

0.1 M glucose
0.1 M KCl
0.6% glucose solution
0.6% NACL solution

Solution :Isotonic solutions have same CONCENTRATION.
Concentration of urea solution
`=(0.6//60)/(100)xx1000=0.1 M`
This concentration is same as 0.1 M glucose.
