A chemist needs to create a series of standard Cu2+(aq)Cu2+(aq) solutions for an absorbance experiment. For the first standard, he uses a pipet to transfer 20.0020.00 mL of a 2.952.95 M Cu2+(aq)Cu2+(aq) stock solution to a 500.0500.0 mL volumetric flask, and he adds enough water to dilute to the mark. He then uses a second pipet to transfer 20.0020.00 mL of the second solution to a 50.0050.00 mL volumetric flask, and he adds enough water to dilute to the mark. Calculate the concentration of the Cu2+(aq)Cu2+(aq) solution in the 50.0050.00 mL volumetric flask.
