Chlorine gas can be produced commercially by passing an electric current through a concentrated solution of sodium chloride (brine). the equation is as follows: 2nacl(aq) + 2h2o(l) → 2naoh(aq) + cl2(g) + h2(g). if the brine contains 250 g nacl, how many moles of cl2 can be produced? a) 2.24 mol cl2 b) 2.0 mol c2 c) 2.14 mol cl2 d) 1.40 mol cl2
