Based on what you have learned about individual relativism (subjectivism), how could a person like Ted Bundy be justified in his actions? Revisit his argument from the Chapter 1 PowerPoint. How might these arguments apply to cultural differences? What is the real message being taught here (obviously not that rape or murder is morally right), but what is the root of the arguments being made in this chapter?

Data Analysis I. State the visible color of the sample that you analyzed. Each of the colored samples contains two dyes. If you analyzed the dyes in your sample before mixing them, what two colors would you see? Which absorbance peak is responsible for each dye? Remember, the color absorbed on the color wheel is opposite of the color transmitted. 2. Obtain a copy of the absorbance vs. wavelength graph from one of your classmates who used a different dye sample. Be sure to give credit to anyone who took data that you use in your report, that is not your own. Do these samples have any individual dye in common? 3. Using the molar mass, convert the ppm to molarity values. The molar mass of a typical dye molecule is 472 g/mol. 4. Create a Beer's law plot standard curve - Absorbance vs. Molarity for the dye you used using Microsoft Excel. All of the data for this graph should be measured at the same wavelength. A section on using Microsoft Excel is included after the supplemental exercises of this laboratory. Absorbance should be on the y-axis and concentration should be on the x-axis. The Beer's law plot should occupy one full page. Make sure to include the wavelength of analysis in the title of the graph. 5. Use Excel to fit a line to your data. Display this equation on your plot with the correlation coefficient (r) value. Standard solutions.
