A 0.6407-g sample containing chloride and iodide ions gave a silver halide precipitate weighing 0.4430 g. This precipitate was then strongly heated in a stream of Cl2 gas to convert the AgI to AgCl; on completion of this treatment, the precipitate weighed 0.3181 g. (Molar Mass: AgCl = 143.32 g/mol, AgI = 234.77 g/mol, Cl = 35.45 g, I = 126.90 g/mol) a. Calculate the mass of chloride and iodide in the sample. b. Calculate the percentage of chloride and iodide in the sample.
