Show your work in details: Cu2+ unknown concentration can be analyzed by electrogravitic analysis according to the following reaction: Cu2+ + H20 Cu(s) +½ 02 + 2H* If the mass of the electrode before starting the reaction is 0.5559g and the volume of Cu2+ solution is130.00 mL. After running the experiment, the mass of the electrode became 1.9967g, find the concentration (M) of Cu (63.55 g/mole) in the sample.
