Chlor-alkali plants electrolyze NaCl to produce the commodity chemicals caustic soda and chlorine gas. Industrial waste effluent released into waterways from these plants can contain trace amounts of mercury. Legally, the effluent can contain up to 2.50 x 10-9 mol/L of mercury. Determine the minimum amount of water, in ML, that must be added to a 1.25 g sample of mercury to dilute the effluent to acceptable levels.
