You are required to prepare 2 L of a solution containing 2.000 x 103 mol/L of Cu2*(aq). Which of the following procedures would produce an appropriate solution? Dissolve 0.2542 g of copper metal in nitric acid, add 2.000 L of deionized water from a volumetric flask and mix well. Dissolve 0.1271 g of copper metal in nitric acid, add 2.000 L of deionized water from a volumetric flask and mix well. Dissolve 0.5000 g of CUSO4.5H,O(s) in deionized water, add to a 2.000 L volumetric flask, dilute to the mark with deionized water and mix well. Dissolve 0.9987 g of CuSO4.5H,O(s) in deionized water, add to a 2.000 L volumetric flask, dilute to the mark with deionized water and mix well.
