let me help
m/M =it/cf

now: m is the mass which is x
while M is the molar mass =63.5
while t is time=7200s (ie 2hrs x3600)
while i is our current=0.193A
finally our c is the charge on copper which is = 2


now input the values your answer would be A= 0.457

You forgot to multiply 120 by 60...without that your time is still in minutes
