Answer
Degree of dissocsavlt is defined as a fraction of total number of moles of an electrolyte that dissociate into its ions at equilibrium. It is denoted by a and represented by, $\begin{aligned} & \alpha=\frac{\text { number of moles dissociated }}{\text { total number of moles of an electrolyte }} \\ & \text { OR } \alpha=\frac{\text { Per cent dissociation }}{100} \end{aligned}$ $\therefore$ Per cent dissociation $=\alpha \times 100$
