$2 \lambda_{A^{3+}}^0 + 3 \lambda_{B^{2-}}^0$

(A) The molar conductivity at infinite dilution for an electrolyte is given by Kohlrausch's law: $\Lambda_m^0 = \nu_+ \lambda_+^0 + \nu_- \lambda_-^0$. For the electrolyte $A_2B_3$,the dissociation reaction is: $A_2B_3 \rightarrow 2A^{3+} + 3B^{2-}$. Here,the stoichiometric coefficients are $\nu_+ = 2$ and $\nu_- = 3$. Therefore,the molar conductivity is: $\Lambda_m^0(A_2B_3) = 2 \lambda_{A^{3+}}^0 + 3 \lambda_{B^{2-}}^0$.
