∵ (W/E)=(Q/96500) ∴ E=(W × 96500/Q)=(2.977 × 96500/10800)=26.6 ∴ Valency = (106.4/26.4)=4

Q. Find the value of charge on metal cation if $10800 C$ of electricity is passed through the electrolytic solution and that deposited $2.977 g$ of metal (At mass $106.4$ ).

$∵ \frac{W}{E} = \frac{Q}{96500}$
$∴ E = \frac{W \times 96500}{Q} = \frac{2.977 \times 96500}{10800} = 26.6$
$∴$ Valency $= \frac{106.4}{26.4} = 4$
