Chemistry - Electrochemistry Question with Solution | TestHub

Calculate the acid dissociation constant for 0.09 M ${\mathrm{CH}}_3\mathrm{COOH}$ if its solution shows a resistance of 50 $\Omega$ when filled in a cell having separation between parallel electrodes of 1.8 cm and electrode cross section area of 10 $\mathrm{c}{\mathrm{m}}^2$.

Given: ${\Lambda }_m^{\circ }[\mathrm{Mg}({\mathrm{CH}}_3\mathrm{COO}{)}_2]=190$, ${\Lambda }_m^{\circ }{\mathrm{MgCl}}_2=240$, ${\Lambda }_m^{\circ }\mathrm{HCl}=425$ (all in S $\mathrm{c}{\mathrm{m}}^2$ $\mathrm{mo}{\mathrm{l}}^{-1}$).
