Initial mass of copper (g) 5.720 Average current (A) 0.386A Final mass of copper (g) 5.920 Time of current application (s) 30.0 min 1. Calculate the total charge, in coulombs (C), that passed through the electrolytic cell. 2. Use your answers from 1 above to calculate the number of electrons transferred to the copper ions. Note: The charge of an electron is 1.602 × 10–19 coulombs per electron. 3. Determine the number of copper atoms deposited. Remember that the electrolysis process uses two electrons to produce one copper atom. 4. Based on the mass of copper deposited, determine the mols of copper deposited (the mass of the electrons is negligible).
