O Macmillan Learning A chemist needs to create a series of standard Cu² (aq) solutions for an absorbance experiment. For the first standard, he uses a pipet to transfer 25.00 mL of a 2.71 M Cu²+(aq) stock solution to a 500.0 mL volumetric flask, and he adds enough water to dilute to the mark. He then uses a second pipet to transfer 20.00 mL of the second solution to a 100.0 mL volumetric flask, and he adds enough water to dilute to the mark. Calculate the concentration of the Cu²+(aq) solution in the 100.0 mL volumetric flask. concentration: M

O Macmillan Learning
A chemist needs to create a series of standard Cu² +(aq) solutions for an absorbance experiment. For the first standard, he uses a
pipet to transfer 25.00 mL of a 2.71 M Cu²+(aq) stock solution to a 500.0 mL volumetric flask, and he adds enough water to
dilute to the mark. He then uses a second pipet to transfer 20.00 mL of the second solution to a 100.0 mL volumetric flask, and
he adds enough water to dilute to the mark. Calculate the concentration of the Cu² (aq) solution in the 100.0 mL
volumetric flask.
