    Which of the following solutions are isotonic with one another?

    A) 0.15 M urea and 0.05 M \[1.22f\]

    B) 0.15M urea and 0.1 M\[f\]

    C) 0.15 M urea and 0.15 M glucose

    D) 0.1\[1.27f\] and 0.05 M \[\text{1}.0\text{1}\times \text{1}{{0}^{\text{5}}}\text{ N}/{{\text{m}}^{\text{2}}}\]

    Correct Answer: C

    Solution :

                    0.15 M urea and 0.15 M glucose solution are isotonic because both on dissociation give only one molecule, while \[{{\sin }^{-1}}\left( \frac{8}{9} \right)\] give two molecules and \[\beta =0.\text{1}\] will give three molecules.
