What volume of oxygen measured at s.t.p would be liberated on electrolysis by 9650 coulombs of electricity?
(Molar volume of gas = 22.4 dm3, F = 96,500 C mol-)
22.4 dm3
11.2 dm3
1.12 dm3
0.560 dm3
Correct answer is D
For a diatomic divalent element like oxygen:
4 faraday (4 * 96,500) = 1 mole of the element = Molar volume of gas = 22.4
: 4 * 96,500 = 22.4
9650 = x
: x = 9650∗22.44∗96,500
x = 0.56dm3
