For a strong electrolyte, $\Lambda_{m}$ increases slowly with dilution and can be represented by the equation $\Lambda_{m} = \Lambda_{m}^{\circ} - Ac^{1/2}$. Molar conductivity values of a solution of strong electrolyte $AB$ at $18^{\circ} C$ are given below:
$c \ [mol \ L^{-1}]$ $0.04$ $0.09$ $0.16$ $0.25$ $\Lambda_{m} \ [S \ cm^2 \ mol^{-1}]$ $96.1$ $95.7$ $95.3$ $94.9$
The value of constant $A$ based on the above data [in $S \ cm^2 \ mol^{-1} / (mol \ L^{-1})^{1/2}$] is . . . . . . .
