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 22.4 L )

Question

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 22.4 L ) (A) 54.9 g (B) 5.4 g (C) 10.8 g (D) 108.0 g

Tardigrade Admin · Accepted Answer

According to faraday's 2 text nd law (WA g/EA g)=(WO2/EO2) (WA g/108)=(((560/22400)) × 32/8) ∴ W Ag =10.8 g

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

54.9 g

5.4 g

10.8 g

108.0 g

According to faraday's $2^{nd}$ law $\frac{W _{A g}}{E _{A g}} = \frac{W _{O_{2}}}{E _{O_{2}}}$
$\frac{W _{A g}}{108} = \frac{( \frac{560}{22400} ) \times 32}{8}$
$∴ W_{A g} = 10.8 g$
