Claudia determines the concentration of sodium hypochlorite, NaOCl, in bleach using a redox titration that requires two steps. First, she acidifies the NaOCl and adds excess iodide to produce iodine. Next, she titrates the iodine using a solution of standardized sodium thiosulfate, Na2S2O3. Claudia observes the end point of the titration after adding 0.751 mL of 0.150 M Na2S2O3 to 0.081 g of a commercial bleach product. Calculate the percent by weight of NaOCl in the bleach sample.
