4. A 0.1405 g solid sample of an organic compound containing bromine is treated in such a way to release the bromine as bromide ions in 50.0 mL of an aqueous solution. A 10.0 mL aliquot of 0.100 F AgNO3 is added to precipitate the bromide ions as AgBr. The dried precipitate has a mass of 0.1027 g. What is the percentage by mass of bromine in the original sample? (Ksp for AgBr is 5.4 x 10-13)
