Q 12 :

The pH and conductance of a weak acid (HX) was found to be 5 and $4 \times 10^{- 5} S$ respectively. The conductance was measured under standard condition using a cell where the electrode plates having a surface area of $1 c m ²$ were at a distance of 15 cm apart. The value of the limiting molar conductivity is ______ $S m ² m o l ⁻ ¹$ . (nearest integer)
(Given : degree of dissociation of the weak acid $(α) ≪ 1)$ [2026]
