The specific conductivity of a saturated solution of AgCl is $3.40\times {10}^{-6}{\text{Ohm}}^{-1}{\text{ cm}}^{-1}{\text{ at 25}}^{\mathrm{o}}\mathrm{C}$. If ${\mathrm{\lambda }}_{{\mathrm{Ag}}^{+}}=62.3 {\mathrm{ohm}}^{-1} {\mathrm{cm}}^2 {\mathrm{mol}}^{-1}$ and ${\mathrm{\lambda }}_{{\mathrm{Cl}}^{-}}=67.7 {\mathrm{ohm}}^{-1} {\mathrm{cm}}^2 {\mathrm{mol}}^{-1}$, the solubility of AgCl at ${25}^{\mathrm{o}}\mathrm{C}$ is
