The conductivity of 0.1 M ethanoic acid is 0.039 S ${\mathrm{m}}^{-1}$. Then the degree of dissociation of ethanoic acid is:

Given ${\lambda }_{{\mathrm{H}}^{+}}^{\circ }$ = 350 S ${\mathrm{cm}}^2$ ${\mathrm{mol}}^{-1}$; ${\lambda }_{\mathrm{C}{\mathrm{H}}_3\mathrm{CO}{\mathrm{O}}^{-}}^{\circ }$ = 40 S ${\mathrm{cm}}^2$ ${\mathrm{mol}}^{-1}$
