**Problem 2.** Calculate the number of grams of CuCl₂·2H₂O solid needed to prepare 25.00 mL of 0.0450 M CuCl₂·2H₂O solution. Show your work in the space below. --- **Problem 3.** Assume you are preparing 25.00 mL of 0.0450 M CuCl₂·2H₂O solution described above by dissolving your calculated amount of CuCl₂·2H₂O in a 25.00 mL volumetric flask. When you measure out the CuCl₂·2H₂O, you have 0.01 g of extra CuCl₂·2H₂O for your exact amount. Calculate the exact concentration of CuCl₂·2H₂O solution you prepared.
