The degree of association (\alpha) of a solute in an electrolytic solution is defined as the ratio of the observed molecular weight of the solute to its true molecular weight. In this question, we are given that the solute is 60% ionized, which means that 40% of the solute remains in the form of molecules. Therefore, the observed molecular weight of the solute is 60% of its true molecular weight.

So, \alpha =\frac{Observed \ molecular \ weight \ of \ solute}{True \ molecular \ weight \ of \ solute} = \frac{0.6}{0.4} = 1.5
