Equivalent conductance at infinite dilution of ${\mathrm{Ca}}^{+2}$ and ${\mathrm{PO}}_4^{-3}$ are ‘X’ $\mathrm{mho} {\mathrm{cm}}^2 {\mathrm{geq}}^{-1}$ and ‘Y’ $\mathrm{mho} {\mathrm{cm}}^{2 }{\mathrm{geq}}^{-1}$ respectively. Molar conductance at infinite dilution of ${\mathrm{Ca}}_3{\left({\mathrm{PO}}_4\right)}_2$ is equal to ……. $\mathrm{mho} {\mathrm{cm}}^2 {\mathrm{mole}}^{-1}$
