On passing a current of \( 1.0 \) ampere for \( 16 \mathrm{~min} \) and \( 5 \mathrm{sec} \) through one litre solution of \( \mathrm{CuCl}_{2} \), all copper of the solution was deposited at cathode. The strength of \( \mathrm{CuCl}_{2} \) solution was (Molar mass of \( \mathrm{Cu}=63.5 \); Faraday constant \( =96,500 \) \( \left.\mathrm{Cmol}^{-1}\right) \)
(a) \( 0.01 \mathrm{~N} \)
(b) \( 0.01 \mathrm{M} \)
(c) \( 0.02 \mathrm{M} \)
(d) \( 0.2 \mathrm{~N} \)
