In a Vollard titration, a 0.5467g bromide containing unknown sample was dissolved, and then 50.00mL of 0.2000M AgNO3 was added to it. The resultant AgBr precipitate was removed and 1.0mL of 0.1000 M Fe3+ was added to the filtrate. Then 30.45mL of 0.2505 M KSCN was necessary to titrate the excess Ag+(aq). What is the w/w% bromide in the original unknown sample?
