When during electrolysis of a solution of $\mathrm{AgNO}_3 9650$ coulombs of charge pass through the electroplating bath, the mass of silver deposited on the cathode will be
$10.8 \mathrm{~g}$
$21.6 \mathrm{~g}$
$108 \mathrm{~g}$
$1.08 \mathrm{~g}$
Solution
No. of moles of silver $=\frac{9650}{96500}=\frac{1}{10}$ moles
$\therefore$ Mass of silver deposited $=\frac{1}{10} \times 108=10.8 \mathrm{~g}$
