    For this problem, we use the Faradays law to relate the mass electroplated and the current passed through. We do as follows:

    60.1 g (1 mol / 196.67 g) (1 mol e - / 1 mol Au) (96500 C / 1 mol e-) = 29486.25 C

    Q = It

    29486.25 = 5t

    t = 5897.85 s = 98.30 min

    Hope this answers the question.
