What is the relation between cell constant,conductivity and electrical resistance?

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.

On which of the following factors does electronic conductance $NOT$ depend?

The resistance of a $0.5 \, M$ solution of an electrolyte in a cell was found to be $50 \, \Omega$. If the electrodes in the cell are $2.2 \, cm$ apart and have an area of $4.4 \, cm^2$,then the molar conductivity (in $S \, m^2 \, mol^{-1}$) of the solution is:

Equivalent conductivity at infinite dilution for sodium potassium oxalate $[(COO^{-})_{2} Na^{+} K^{+}]$ will be (given molar conductivities of oxalate,$K^{+}$ and $Na^{+}$ ions at infinite dilution are $148.2$,$50.1$,and $73.5 \ S \ cm^{2} \ mol^{-1}$ respectively).
