Fremstilling af I2

   M(I₂) = 253,81 g/mol

    1 mol = 253,80894 g

     0.005 mol = 0.005·(253,80894 g) = 1,26905 g

dvs
          0.005 M           afhængigt af det ønskede volumen

                                         1,26905 g i 1000 mL

                                          0,634525 g i 500 mL

                                          0,317263 g i 250 mL

                                          0,158631 g i 125 mL
