Hope this helps, have a great day ahead!
Answer:
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
I believe the answer is A. <span />
