4) You will need to create a Calibration curve with six absorbance data points ranging from 0 to 0.6. Using 50mL volumetric flasks and 5 mL fo the FRAP reagent in each flask, designs procedure that allows you to create this curve, Your procedure must describe whether a stock solution is needed or not, and if needed describe how to prepare the stock solution. Supporting info: For questions 3 and 4, you will be asked to design procedures using the following materials. You may or may not need all of these chemicals or glassware.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
