Q. A certain charge liberates $0.8\ gm$ of $O_{2}.$ The same charge will liberate how many $gm$ of silver
A) $108\ gm$
B) $10.8\ gm$
C) $0.8\ gm$
D) $\frac{108}{0.8}gm$
Explanation
(b) $\frac{Mass\ of\ O_{2}\ ions}{Mass\ of\ Ag\ ions} = \frac{Chemical\ equivalent\ of\ O_{2}}{Chemical\ equivalent\ of\ Ag}$
$\Rightarrow \frac{0.8}{m} = \frac{8}{108} \Rightarrow m = 10.8\ gm$
