A student weighed 0.2440 grams of sample of a recently synthesized cobalt amine bromide compound. After dissolving in 120mL of acidified water, she added 2.55 grams of AgNO3 to precipitate any free Br-. The precipitate was found to weigh 0.3700 grams. Calculate the %Br- in the sample. MW Cl- 35.45 g/mol; MW Br- 79.91 g/mol; MW Ag 107.87 g/mol
