At infinite dilution the molar conductance of `AI^(+3)` and `SO_(4)^(-2)` ion are 189 and `160 Omeg

At infinite dilution the molar conductance of `AI^(+3)` and `SO_(4)^(-2)` ion are 189 and `160 Omega^(-1) cm^(2) \"mole\"^(-1)` resoectively. Calculate the equilvalent and molar conductivity at infinite dilute of `AI_(2)(SO_(4))_(3)`.
