    1.) The measured absorbance of a sample in a spectrophotometer is 0.704. What percentage of the incident light is being transmitted?

    2.) A sample containing 0.0250 M concentration of a dye in a cell of 1 cm^2 cross section has a measured absorbance of 1.012 at 650 nm. Calculate the instrumental constant k for the spectrophotometer at that wavelength.
