Given that 3.582 g of copper (II) chloride are dissolved in 2.478 litres of deionized water, answer the following: 1) How many moles of copper (II) ions are present in the sample? 2) How many total copper (II) ions are present in sample? 3) What is the molar concentration of chloride ion in the final solution (assuming complete dissociation)? 4) What is the percentage yield if 122.5 mg of a light blue-green solid is collected after 100.00 mL of this solution is combined with 25.0 mL of 0.0433 M Na3PO4 solution? (You must calculate the theoretical yield for the reaction).
