Weighing a copper atom in an electrolysis experiment. 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. If it is found that a current of
1.00 A flowing for 3600 s deposits 1.185 g of copper,
find (a) the number of copper atoms deposited,
(b) the weight of a copper atom, and (c) the molar
mass of copper.
