A 100mM/L solution of Free-chlorine stock solution was used to make up 6 standard solutions (known concentration). See the table below with gives the test tube number, the amount of stock solution used and the amount of distilled water used to make up these solutions. Table 1: Concentration of Standard Solutions

Use the M1V1 = M2V2 formula where M1 is the molarity of the stock solution, V1 is the volume of stock solution, and V2 is the final volume of the solutions (10.00 mL) to calculate the concentration of Free-chlorine in each of the 6 solutions. Record the calculated numbers into the table above. Ex: Test tube 0

M1= 100. mM V1 = 1.00 mL V2 = 10.00 mL

(100. mM) (1.00 mL) = M2 (10.00 mL)

M2 = 10.00 mM
