  1. As weight/volume (w/v) the concentration is
    120 g NaOH/800 cc = ? g/cc.

    As weight/eight (w/w) and assuming the density of water as 1.00 g/cc, then the mass of the 800 cc H2O is 800 grams + 120 g NaOH = 929 grams total weight so concentration is 120 g NaOH/920 g solution = ? g NaOH/gram solution.
