Question: 2. A 1.000 g sample containing chlorides, iodides and inert materials was treated with dilute nitric acid followed by AgNO3. A precipitate of AgCl (143.45)

2. A 1.000 g sample containing chlorides, iodides and inert materials

2. A 1.000 g sample containing chlorides, iodides and inert materials was treated with dilute nitric acid followed by AgNO3. A precipitate of AgCl (143.45) and AgI (234.77) was produced and weighs 0.9238 g. On heating in a current of Cl2, the AgI is converted to AgCl, and the mixture of precipitate weighs 0.6738 g in weight. Find the percentage of a) Nal (149.89) and b) NaCl (58.44) in the sample. (8 points)
