Conductivity of an electrolytic cell is affected by factors such as the concentration of the electrolyte, the nature of the electrolyte, and the nature of the solvent. However, the nature of the electrode used does not directly affect the electrolytic conductance of a solution.
If the molar conductivity ($\Lambda_m$) of a 0.050 mol $L^{–1}$ solution of a monobasic weak acid is 90 S $cm^{2} mol^{–1}$, its extent (degree) of dissociation will be:
[Assume: $\Lambda^0$ = 349.6 S $cm^{2} mol^{–1}$ and $\Lambda^0_{\text{acid}}$ = 50.4 S$ cm^{2} mol^{–1}$]
