The conductance of a 0.0015 M aqueous solution of a weak monobasic acid was determined by using a conductivity cell consisting of platinized Pt- electrodes. The distance between the electrodes is 120 cm with an area of cross-section of 1$\mathrm{c}{\mathrm{m}}^2$. The conductance of this solution was found to be$5\times 10^{-7}$S. The pH of the solution is 4. The value of limiting molar conductivity$\left({\mathrm{\Lambda }}_{\mathrm{m}}^{\mathrm{o}}\right)$if this weak monobasic acid in aqueous solution is$\mathrm{Z}\times 10^2$S$\mathrm{c}{\mathrm{m}}^2\mathrm{m}\mathrm{o}{\mathrm{l}}^{-1}$. The value of Z is
