Observations and Questions

[6] Based on your data and observations from procedure II and procedure III, which solution has the highest concentration? Explain your answer.

[7] Concentration Calculation: Using your Trial 1 data from procedure II and procedure III, and the known concentration of guanine (see Activity Form tab), calculate the concentration of the cytochrome c solution. Hint: See the Summary of Needed Formulas section under the Background tab and information found under the Activity Form tab.
