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?

  • Chem - ,

    7.2 amps x 90 min x (60 sec/min) = about 40,000 coulombs but you do it more accurately.
    96,485 coulombs will deposit 58.7/2 grams Ni. So how much will 40,000 deposit.
    (58.7g/2) x (40,000/96,485) = ? g Ni.
