A 0.6 % solution for urea (molecular mass =60) would be isotonic with

Options

  1. A0.1 M glucose solution
  2. B0.6 % solution of glucose
  3. C0.1 M KCl solution
  4. D0.6 % KCl solution

Correct answer

A. 0.1 M glucose solution

Step-by-step solution

Molarity of 0.6 % solution = 0.6 60 1000 100 =0.1 M From, the options, we know that KCl will dissociate as it ionic. Therefore, option (c) and (d) are incorrect. And, molarity of 0.6 % glucose = 0.6 180 1000 100 =0.3 M So, 0.6 % solution of urea is isotonic with 0.1 M glucose solution.
