a 3.00ml bleach sample is mixed with potassium iodide and acid to completely form triiodide ions. You then titrate the I3- ions with thiosulfate (S2O32-) solution, that has been determined to be 0.1306 M. The end point is reached when 31.52 ml of the thosulfate solution is added. What is the molar concentration of the bleach solution? What is its mass percent?
