5.00 mL of commercial bleach was diluted to 100.0 mL.
25 mL of that diluted sample was titrated with 4.56 mL of 0.10 M S2O3^2-.
What is the concentration of the hypochlorite in the original bleach solution?
Assume the density of commercial bleach is 1.08 g/mL.
Calculate the average percent mass of NaClO in the commercial bleach.
