You are required to prepare 5 L of a solution containing 1.000 x 103 mol/L of Cu2"(aq). Which of the following procedures would produce an appropriate solution? O Dissolve 0.0636 g of copper metal in nitric acid, add to a 5.000 Lvolumetric flask, dilute to the mark with deionized water and mix well. O Dissolve 1.248 g of CuSO.5H,0(s) in deionized water, add to a 5.000 L volumetric flask, dilute to the mark with deionized water and mix well.

In the laboratory, a student was tasked to prepare a stock solution of HCl for titration. The available analytical grade HCl solution in the stock room was labelled 35% w/v HCl. The student proceeded to prepare the stock solution by mixing 10mL of the HCl solution with 490mL of analytical grade water. Then, the solution was further diluted by adding 5mL, since the total volume of the solution did not reach the 500mL etched mark on the volumetric flask. To prepare the titrant, the student mixed 10mL of the stock solution, then added 40mL of analytical grade water. The titrant was subsequently used to determine the concentration of two titrand. *Use the table as a reference 1. What is the normality of the available HCl reagent in the stock room?* 5.08 N 10.15 N 20.3 N 11.0 N None of the choices 2.
