Question 3 Why is it necessary to run a blank before measuring the absorbance of a sample? O To account for the absorbance caused by the cuvette alone. So that scattered light will be filtered before hitting the photodetector. To account for the absorbance caused by the cuvette and the solvent O To allow the lamp and electronics of the spectrophotometer to warm up before taking the sample absorbance reading.

Q2-) Compare the sample strengths used in fluorescence spectroscopy and UV-Vis techniques.
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?
