Time=345.7 min

Explanation:

It is an example for Faraday's first law of Electrolysis

It states that the amount of substance deposited is directly proportional to the amount of electricity passed.

W=Zit

Z=E/96500

W = E it/96500

And E=58.7 (molar mass of Ni) / 2 (charge on Ni) = 29.3

t=W96500/E i

= 29.6x96500/29.3x4.7

= 20742.1 sec

=345.7 min
