A 4.0 M aqueous solution of NaCl is prepared and 500 mL of this solution is electrolysed. This leads to the evolution of chlorine gas at one of the electrodes. (Na = 23, Hg = 200, 1 F = 96500 C) The following examples illustrate a typical case, involving chemical/electrochemical reaction, which requires a clear understanding of the mole concept. If the cathode is a Hg electrode, the maximum weight (g) of amalgam formed from this solution is
