In an electroplating process, copper (ionic charge +2e, atomic weight 63.6 g/mol) is deposited using a current of 10.0 A. What mass of copper is deposited in 10.0 minutes? Avogadro's number is 6.022 × 1023 molecules/mol and e = 1.60 × 10-19 C.
Simran C.
Calculate the mass of copper (in grams) produced in 5.41 hours by the electrolysis of molten CuCl2 if the electrical current is 10.1 A. You may assume the molar mass of elemental copper is 63.546 g/mol.
