Liquid Solution

A solution of \(\mathrm{KCl}(\mathrm{M}=74.5 \mathrm{~g} \mathrm{~mol}^{-1})\) containing \(1.9 \mathrm{~g}\) per \(100 \mathrm{~mL}\) of \(\mathrm{KCl}\) is isotonic with a solution of urea \((\mathrm{M}=60.0 \mathrm{~g} \mathrm{~mol}^{-1}\)) containing \(3 \mathrm{~g}\) per \(100 \mathrm{~mL}\) of urea. The degree of dissociation of \(\mathrm{KCl}\) is:
[Assume both the solutions are kept at same temperature]
