An electrolytic cell consists of a 100.0-g strip of copper in 0.200 M Cu(NO3)2 and a 100.0-g strip of Cr in 0.200 M Cr(NO3)3. The overall reaction is: 3Cu(s) + 2 Cr³+ (aq) →→→3Cu²+ (aq) + 2Cr(s) E = -1.083 V An external battery provides 3 amperes for 70 minutes and 20 seconds with 100% efficiency. What is the mass of the copper strip after the battery has been disconnected?
