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?
Conclusion 5: You are tasked with analyzing a suspiciously pink sample of drinking water to establish if it has unsavory levels of MnO4-contamination.
