Achemist 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 2.96 m cu2 (aq) stock solution to a 250.0 ml volumetric flask and 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 adds enough water to dilute to the mark. calculate the concentration of the cu2 (aq) solution in the 100.0 ml volumetric flask.
