Balance the equation and answer in terms of

Question

moles.
Chlorine gas can be produced commercially
by passing an electric current through a con-centrated solution of sodium chloride (brine).
The unbalanced equation is
NaCl(aq) + H2O(`) !
NaOH(aq) + Cl2(g) + H2(g) .
If the brine contains 389 g of NaCl, how
much Cl2 can be produced?
Answer in units of mol
