How many grams of Ni would be electroplated if a constant current of 7.2 amperes is passed through a solution of NiSO4 for 90.0 min?

How many grams of Ni would be electroplated if a constant current of 7.2 amperes is passed through a solution of NiSO4 for 90.0 min?

= 7.2 amps `\times` 90 min `\times` (`"60 sec"/"min") = 40,000 Approx

= 96,485 coulombs will deposit `"58.7"/"2"` grams Ni.

= (`"58.7g"/"2") `\times` (`"40,000"/"96,485"`)

= 12g Ni.
