Question

number of coulombs of electricity passed when 6.023×10²² electrons were passed during the process of electrolysis​

Answer 1

Explanation:

Given current, i = 1 Amp and time taken, t = 60sec

So, charge = i × t = 1 × 60 = 60 Coulombs

∵ 96500 C charges are equivalent 1 mole of electrons

∴ 1 C charge is equivalent with 1/96500 mole of electrons

∴ 60C charges are equivalent with 60/96500 mole of electrons

Hence, mole of electrons = 6/9650

so, the number of electrons = 6/9650 × 6.023 × 10²³

= 0.003744 × 10²³

= 3.744 × 10²⁰
