1. Define the following terms: a. Serial Dilution b. UV-Vis Spectroscopy C. Beer's Law 2. Determine the molarity (mM) for a solution of NasPO prepared by diluted 100 ml of a 0.33 M solution of NaaPOs to 1.00 L 3. If 5.00 ml of the 1.0 L solution prepared in question 2 was diluted to 50.0 mL, what would be the concentration (mM) of NasPOs in this new solution? 4. The absorbance of a 0.100 mM solution of a dye in a 1.00-cm cell is 0.982 at 420 nm. Calculate the molar absorptivity constant (M1cm1) for this dye. 5. What would be the absorbance of a 0.0500 mM solution of this dye at 420 nm? Assume a 1.00-cm cell is used for this measurement.
