For the exercise in this topic, base your answers on the potentials listed in Table 6M.1 or Appendix 2B, with the exception of the reduction and oxidation of water at pH = 7:A total charge of 67.2 kC is passed through an electrolytic cell. Determine the amount of substance produced in each case:

(a) The mass (in grams) of silver metal from a silver nitrate solution;

(b) The volume (in liters at 273 K and 1.00 atm) of chlorine gas from a brine solution (concentrated aqueous sodium chloride solution);

(c) The mass of copper (in grams) from a copper(II) chloride solution.
