The standard electrode potentials $E^{\circ}(\mathrm{V})$ for $\mathrm{Li}^{+} / \mathrm{Li}, \mathrm{Na}^{+} / \mathrm{Na}$ respectively are

The molar conductivity of 0.02 M solution of an electrolyte is $124 \times 10^{-4} \mathrm{~S} \mathrm{~m}^2 \mathrm{~mol}^{-1}$. What is the resistance of same solution (in ohms), kept in a cell of cell constant $129 \mathrm{~m}^{-1}$ ?

If the degree of dissociation of formic acid is $11.0 \%$, the molar conductivity of 0.02 M solution of it is (Given, $\lambda^{\circ}\left(\mathrm{H}^{+}\right)=349.6 \mathrm{~S} \mathrm{~cm}^2 \mathrm{~mol}^{-1}$ $\lambda^{\circ}\left(\mathrm{HCOO}^{-}\right)=54.6 \mathrm{~S} \mathrm{~cm}^2 \mathrm{~mol}^{-1}$ )
