Weight of Ag (at wt. = 108) displaced by a quantity of electricity that displaced by a quantity of electricity that displaces 5600 mL `O_(2)` at STP-

A

5.4 g

B

10.8 g

C

54.9 g

D

108.0 g

Text Solution

Verified by Experts

The correct Answer is:
D
Electricity required for the production of 1 g-eq or 8g of
`O_(2)=1F`.
At STP,
`"32 g of oxygen "-="22400 mL of "O_(2)`.
`therefore" 8 g of oxygen "-="5600 mL of "O_(2)`.
`therefore" Mass of Ag deposited "="1 g eq of Ag = 108 g."`
