Question

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 20.00mL of a 2.30M 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 10.00mL 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.
