Explain how many milligrms of se were contained in sample

Reference no: EM13269149

A 5.00-mL aqueous suspension of elemental selenium was treated with 25.00 mL of ammoniacal 0.0360 M AgNO3. After the reaction was complete, nitric acid was added to dissolve the AgSO3 but not the AgSe. The Ag+ from the dissolved Ag2SeO3 and the excess reagent required 16.74mL of 0.01370 M KSCN in a Volhard titration. How many milligrms of Se were contained in each milliliter of sample?
