Question

A $0.6\%$ solution of urea $(M.W.=60)$ would be isotonic with:

• A. $0.1\text{M}$ NaCl
• B. $0.1\text{M}KCl$
• C. $0.6\%$ Glucose solution
• D. $0.6\%KCl\text{solution}$

Answer 1

The correct option is C $0.6\%$ Glucose solution

Isotonic solutions will have same osmotic pressure. Urea is a non-electrlolyte solution and glucose is a non-electrolyte among the given options.
Hence, C is the correct answer.
