Electrochemistry Part 2

The pH and conductance of a weak acid ( HX ) was found to be 5 and 4×10−5S, respectively. The conductance was measured under standard condition using a cell where the electrode plates having a surface area of 1cm2 were at a distance of 15 cm apart. The value of the limiting molar conductivity is ____ Sm2mol−1. (nearest integer)
(Given : degree of dissociation of the weak acid (α)≪1 )
