Maybe you can divide the volts its twelve if you do that but itll show you how much to double it by

Answer:
75.5g
Explanation:
From the ionic equation, we can write
![CU^{2+}+SO^{2-}_{4}\\](https://tex.z-dn.net/?f=CU%5E%7B2%2B%7D%2BSO%5E%7B2-%7D_%7B4%7D%5C%5C)
next we find the number of charge
Note Q=it
for i=8.5A, t=3.75 to secs 3.75*60*60=13500secs
hence
![Q=8.5*13500\\Q=114750C](https://tex.z-dn.net/?f=Q%3D8.5%2A13500%5C%5CQ%3D114750C)
Since one faraday represent one mole of electron which equal 96500C
Hence the number of mole produced by 114750C is
114750/96500=1.2mol
The mass of copper produced is
![mol=\frac{mass}{molar mass} \\mass=mole*molar mass\\mass=1.2*63.5\\mass=75.5g](https://tex.z-dn.net/?f=mol%3D%5Cfrac%7Bmass%7D%7Bmolar%20mass%7D%20%5C%5Cmass%3Dmole%2Amolar%20mass%5C%5Cmass%3D1.2%2A63.5%5C%5Cmass%3D75.5g)
Hence the amount of copper produced is 75.5g
