6.0 g of a sample containing and is dissolved in 100 mL water. A 10 mL portion of this solution on treatment with solution results in complete precipitation of and giving 0.9065 gram of precipitate. The precipitate thus obtained was shaken with dilute solution of NaBr where all AgCl gets converted into AgBr. Mass of the new precipitate was found to be 1.005 g. Determine % mass of and in the original sample.
