Chemistry - Ionic Equilibrium Question with Solution | TestHub

Calculate the solubility product of$\mathrm{C}{\mathrm{o}}_2\left[\mathrm{F}\mathrm{e}\right(\mathrm{C}\mathrm{N}{)}_6]$in water at$25°$C.
Given, conductivity of saturated solutions of$\mathrm{C}{\mathrm{o}}_2\left[\mathrm{F}\mathrm{e}\right(\mathrm{C}\mathrm{N}{)}_6]$is$\text{2}\text{.06}\text{×}{\text{10}}^{-\text{6}}{\text{Ω}}^{-\text{1}}{\text{cm}}^{-\text{1}}$and that of water used is$\text{4}\text{.1}\text{×}{\text{10}}^{-\text{7}}{\text{Ω}}^{-\text{1}}{\text{cm}}^{-\text{1}}$. The ionic molar conductivities of$\mathrm{C}{\mathrm{o}}^{2+}$and$\left[\mathrm{F}\mathrm{e}\right(\mathrm{C}\mathrm{N}{)}_6{]}^{4-}$are$\text{86}\text{.0}\text{Ω}{\text{cm}}^{\text{2}}{\text{mol}}^{-\text{1}}$and$\text{444}\text{.0}{\text{Ω}}^{-\text{1}}{\text{cm}}^{\text{2}}{\text{mol}}^{-\text{1}}$, respectively.
