Iodide concentration in a 0.6712-g sample was analyzed by titrating it with exactly 50.00 mL of 0.05619 M silver nitrate standard solution. This precipitated all the iodide ions in the solution. The unreacted standard solution was back titrated and reach the end point with exactly 34.15 of 0.05322 M potassium thiocyanate. How many moles iodide are in the sample? 9.393 x 10-4 moles 2.810 x 10-3 moles None of the given choices 1.870 x 10-3 moles
