    For a strong electrolyte, Λm\Lambda_{m} increases slowly with dilution and can be represented by the equation Λm=Λm∘−Ac1/2\Lambda_{m} = \Lambda_{m}^{\circ} - Ac^{1/2}. Molar conductivity values of the solutions of a strong electrolyte AB at 18∘C18^{\circ}C are given below :
    cc (mol L−1mol\ L^{-1})0.040.090.160.25
    Λm\Lambda_{m} (S cm2 mol−1S\ cm^{2}\ mol^{-1})96.195.795.394.9
    The value of the constant A based on the above data [in S cm2 mol−1/(mol/L)1/2S\ cm^{2}\ mol^{-1}/(mol/L)^{1/2} unit] is ____\_\_\_\_ .
