The following must be included in your results and discussion section: 1. What is the maximum excitation and emission wavelength? 2. Find the absorption and emission spectrum of riboflavin in the literature. Do your observations match? Cite your source appropriately. 3. A figure with the emission and excitation scans, with the complementary excitation and emission wavelength mentioned in the caption or legend (i.e. "The emission of riboflavin with an excitation wavelength of 340nm ", etc.) 4. A figure for the calibration curve for your standards, with equation and R2 on the graph. 5. Does the fluorescence intensity behave in a linear fashion with concentration in this concentration range? Explain. 6. What unknown number do you have? What is the concentration of your unknown? What is its standard deviation and relative standard deviation? Show your calculations for these. You do not need to report other group member's results, only your own. Part of your grade will be based on the accuracy of your measurement
