See the example calculation in the lab manual. Suppose that you determine that the molarity of your sodium thiosulfate solution is 0.100 M. Suppose 11.78 mL of the same thiosulfate solution reacts with the iodine replaced by 20.00 mL of an unknown solution of sodium hypochlorite. Calculate the weight, in grams, of available Cl in a liter of the unknown solution. Enter your answer as a decimal number with 3 decimal places.
