lodide (atomic mass 126.9 g/mol) in water was determined by the Volhard method. A 20.00 mL aliquot of the water was treated with 25 mL of 0.1281 M AgNO3 solution. After heating, the water sample was titrated with standard 0.121 M KSCN solution and 4.68 mL was required to reach the red Fe(SCN)2+ end point. Calculate the concentration (g/L) of iodide in the water sample.
