Calculate the quantity of electricity in coulombs required to liberate 10g of copper from a copper compound [Cu=64, F = 96500 Cmol-1]

A. 32395.5
B. 30156.3
C. 60784.5
D. 15196.5

Correct Answer:

Option B = 30156.3

Explanation

Cu → Cu²+ + 2e
64g Cu requires 2 x 96500 coloumbs 10g Cu requires x columbs

x = (10x2x96500)/64 =30156.3
