potato is added to the 50 mL of water. For example, 57 mL - 50 mL = 7 mL of displacement. 5. Remove Sample A from the graduated cylinder and place it in Test Tube A. If any water was lost in the graduated cylinder, refill it to the 50 mL graduation mark. 6. Place the second potato strip (Sample B) into the graduated cylinder. Record the initial displacement in Table 3. 7. Remove Sample B from the graduated cylinder and place it in Test Tube B. If any water was lost in the graduated cylinder, refill it to the 50 mL graduation mark. 8. Repeat Steps 2 - 7 for the second potato type, using the remaining test tubes in the test tube rack. 9. Use a pipette to add water to each of the test tubes with the A samples in them until the water covers the potato strips. 10.Refer to the instructions provided on the bottle with 16 g of sodium chloride in it to create a 20% sodium chloride solution. Use a pipette to add the 20% sodium chloride solution to each of the test tubes with the B potato samples in them until the solution covers the potato strips. 11.After an hour, pour out the liquid from the test tubes. 12.Repeat Steps 4 - 7 for each sample and type, and record the final displacement values in Table 3. 13.Complete the last column of Table 3 by subtracting the initial displacement from the final displacement.

    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.
