A standard experiment involves passing a current of several amperes through a copper sulfate solution (CuSO4) for a period of time and determining the mass of copper plated onto the cathode. It is found that a current of 1.00 A flowing for 3600 s deposits 1.185 g of copper. Determine: (a) the number of copper atoms deposited, (b) the weight of a copper atom, and (c) the molar mass of copper.
