A student determined the concentration of NaOCI in a commercial bleach sample using the same technique described in section "F" of the Halogens and Their Compounds lab. The student required 18 drops of 0.01M Na,S203 to reach the end point. What is the concentration (reported in molarity) of NaOCI in the bleach sample?
