The answer is 5.36 Hr.
According to Faraday's law,
W=(ECt) / 96500
Where W mass of metal deposited = number of moles x molar mass
=5.00 mol x 63.54 (g/mol)
=317.7 g
E= Equivalent weight of Cu =63.54/2=31.77C
current= 50 A
time taken ,t = ?
Plug the values we get,
t= 96500 W/EC
19300s x ( 1 min/60s) x(1 hr/60min)
t=5.36 hr
