The conductivity of a saturated solution of $AgCl$ at $288 \ K$ is $1.382 \times 10^{-6} \ \Omega^{-1} \ cm^{-1}$. Find its solubility in $g \ L^{-1}$. The ionic conductivities of $Ag^+$ and $Cl^-$ at infinite dilution are $61.9 \ \Omega^{-1} \ cm^2 \ mol^{-1}$ and $76.3 \ \Omega^{-1} \ cm^2 \ mol^{-1}$ respectively.

What is the molar conductivity at infinite dilution of $CaCl_{2}$,if the molar conductivity of $Ca^{2+}$ ion and $Cl^{-}$ ion at infinite dilution is $119$ and $71 \ \Omega^{-1} \ cm^{2} \ mol^{-1}$ respectively?

Conductivity of $0.001 \ M$ aqueous solution of $Na_2SO_4$ is found to be $2.6 \times 10^{-3} \ S \ cm^{-1}$ at $25 \ ^oC$. If limiting molar conductance of $Na^+$ is $50 \ S \ cm^2 \ mol^{-1}$,then limiting molar conductance of $SO_4^{2-}$ will be .............. $S \ cm^2 \ mol^{-1}$ (neglect conductivity of water).
