<span>88(60) 24(365) that should be the answer after you figure it out.</span>
It take 0.54 hours to deposit 6.36g of copper
<h3>Further explanation</h3>
Faraday's Law I
"The mass of the substance formed at each electrode is proportional to the electric current flowing in the electrolysis
W = e.i.t / 96500

e = equivalent = Ar / valence
i = current, A
t = time, s
W=6.36 g
e = 63.5 : 2 =31.75
i = 10 A

The answer to your question would be A. hope this helps...
Components in a pure substance do not have to be in definite ratios.
