\( \mathrm{Zn} \)-amalgam is prepared by electrolysis of aqueous \( \mathrm{ZnCl}_{2} \) using \( \mathrm{Hg} \) cathode \( (9 \mathrm{gm}) \). How much current is to be passed through \( \mathrm{ZnCl}_{2} \) solution for 1000 seconds to prepare a \( \mathrm{Zn} \) amalgam with \( 25 \% \mathrm{Zn} \) by wt. (Atomic mass of \( \mathrm{Zn}=65.4 \) )?
(a) \( 5.6 \mathrm{amp} \)
(b) \( 7.2 \mathrm{amp} \)
(c) \( 8.85 \mathrm{amp} \)
(d) \( 11.2 \mathrm{amp} \)
