Resistance of $\displaystyle 0.2$ M solution of an electrolyte is $\displaystyle 50 \Omega$. The specific conductance of the solution is $\displaystyle 1.4 \mathrm{~S} \mathrm{~m}^{-1}$. The resistance of $\displaystyle 0.5$ M solution of the same electrolyte is $\displaystyle 280 \Omega$. The molar conductivity of $\displaystyle 0.5$ M solution of the electrolyte in $\displaystyle \mathrm{S} \mathrm{m}^2 \mathrm{~mol}^{-1}$ is :
