The sulphur content of a steel sample is determined by converting it to H_(2)S gas, absorbing the H_(2)S in 10 mL of 0.005 M I_(2) and then back titrating the excess I_(2) with 0.002 M Na_(2)S_(2)O_(3) . If 10 mL Na_(2) S_(2)O_(3) is required for the titration , how many milligrams of sulphur are contained in the sample ?
