Chlorine is prepared industrially by passing an electric current through brine, a concentrated solution of sodium chloride.
2NaCl + 2H2O → 2NaOH + Cl2 +H2
All three products are commercially valuable. If 1500 g of a brine solution that is 24% NaCl by mass is used, how many grams of each product can be produced?

How much energy (in kilojoules) is released when 15.3 g of steam at 115C is condensed to give liquid water at 75C? The heat of vaporization of liquid water is 40.67 kJ/mol, and the molar heat capacity is 75.3 J/ (k*mol) for the liquid and 33.6 J / (k*mol) for the vapor.

I don't get this at all!!
