Electrochemistry

For strong electrolyte $\Lambda_m$ increases slowly with dilution and can be represented by the equation

\(\Lambda_m = \Lambda_m^\circ - A c^{1/2}\)

Molar conductivity values of the solutions of strong electrolyte AB at 18°C are given below :

c [mol L-1]	0.04	0.09	0.16	0.25
$\Lambda_m$ [S cm2 mol-1]	96.1	95.7	95.3	94.9

The value of constant A based on the above data [in S cm² mol^-1/(mol/L)^1/2] unit is ________.
