Balance the equation and answer in terms of moles.Chlorine gas can be produced commercially by passing an electric current through a concentrated solution of sodium chloride (brine). The unbalanced equation is NaCl(aq) + H2O(l) → NaOH(aq) + Cl2(g) + H2(g). If the brine contains 320 g of NaCl, how much Cl2 can be produced?
