At a particular temperatur , the ratio of molar conductance of specific conductance of 0.01 M NaCl solution is

Which of the following is not a conductor of electricity?

For a cell involving two electron changes, $E_{\text {cell }}^{\circ}=03 \mathrm{~V}$ at $25^{\circ} \mathrm{C}$. The equilibrium constant of the reaction is

By passing electric current, $\mathrm{NaClO}_3$ is converted in to $\mathrm{NaClO}_4$ according to the following equation

$$ \mathrm{NaClO}_3+\mathrm{H}_2 \mathrm{O} \longrightarrow \mathrm{NaClO}_4+\mathrm{H}_2 $$

How many moles of $\mathrm{NaClO}_4$ will be formed when three Faradays of charges is passed through $\mathrm{NaClO}_3$ ?
