A 2.0 molar 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 (atomic mass: Na = 23, Hg = 200, 1 faraday = 96500 coulomb). If the cathode is a Hg electrode, the maximum weight (in gram) of amalgam formed from this solution is
