The weight of silver (at wt. $= 108$ ) displaced by a quantity of electricity which displaces 560 mL of $O_{2}$ at STP will be
(Volume of 1 mole of gas at STP is 22.4 L)

Options:

Answer:

Solution:

According to faraday's 2nd law $\frac{w_{A g}}{E_{A g}} = \frac{w_{O_{2}}}{E_{O_{2}}}$
$\frac{w_{A g}}{108} = \frac{(\frac{560}{22400}) \times 32}{8}$
$∴$ $w_{A g} = 10.8 g$
