Answer:

21.89 g

Explanation:

i = 15 A

time = 80 minutes = 80 x 60 = 4800 second

Electro chemical equivalent of nickel, Z = 0.000304 gram per ampere second

Use the Faraday's law of electrolysis

m = z i t

where, m is the mass deposited, i be the current, z be the electro chemical equivalent and t be the time taken

m = 0.000304 x 15 x 4800

m = 21.89 g

Thus, the mass f nickel deposited is 21.89 g.
