3. A student followed the procedure of this experiment to determine the percent NaOCI in a commercial bleaching solution that was found in the basement of an abandoned house. The student diluted 50.00 mL of the commercial bleaching solution to 250 mL in a volumetric flask, and titrated a 20-mL aliquot of the diluted bleaching solution. The titration required 35.46 mL of 0.1052M Na₂S₂03 solution. A faded price label on the gallon bottle read $0.79. The density of the bleaching solution was 1.10 g mL-¹. a. Calculate the number of moles of S₂032 ion required for the titration. b. Calculate the number of moles of 12 produced in the titration mixture. c. Calculate the number of moles of OCI" ion present in the diluted bleaching solution titrated.
