A 4.0 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 coulombs)


The total number of moles of chlorine gas evolved is
(A) 0.5 (B) 1.0
(C) 2.0 (D) 3.0
