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).
A. If the brine contains 221 g of NaCl, how much Cl2 can be produced?
B. How much H2 can be produced?
