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 $1{\mathrm{cm}}^2$. The conductance of this solution was found to be $5\times 10^{-7}\mathrm{S}$. The pH of the solution is 4. The value of limiting molar conductivity ( ${\Lambda }_{\mathrm{m}}^{\circ }$ ) of this weak monobasic acid in aqueous solution is $\mathrm{Z}\times 10^2{\mathrm{Scm}}^2{\mathrm{mol}}^{-1}$. The value of Z is
