2. ] You make 150.0 mL of a copper(II) sulfate solution but forget to cover it before leaving for the day. The next class, you measure the volume and find that you only have 132.0 mL remaining. You didn’t record the initial concentration, but you measure the absorbance of the remaining solution at 620 nm and find that it is 0.386. You also construct the following calibration curve for CuSO4: Standard solution Abs620 0.50 M 0.424 0.40 M 0.336 0.30 M 0.247 0.20 M 0.159 (refer to image) a. What is the value for k (in Beer’s Law)?

Prepare a 1:200 dilution of the 20 mM Coomassie solution to measure the max wavelength—you need 2 ml for the absorbance measurement but the dilution does not matter as long as the absorbance is in the range of 0.2 to 0.6. Set the initial wavelength at 450 nm. Blank the spec with a tube containing 2 ml water. Use the 1000 ul pipette for water because you need to deliver the same amount of water in each tube for the next exercise. Why is it when the calculations are done for the given values above, the value for ml is 0.01 for coomassie blue?
