7. Create a bar graph showing the initial mass and final mass for each dialysis tubes. Paste that graph here (screenshot or insert excel graph). The "y" axis should indicate mass in grams, the "x" axis the tubes, label the first group "initial" and the second group "final," and be sure the exact measurement is shown at the top of each bar.

8. Which dialysis tubes had little or no change in mass after 24 hours? Why didn't the mass of these tubes change?

9. Why is pure water used as a control group?

10. How do you know that osmosis was the transport that took place in this lab? Describe the process and why (utilize concepts from the lecture notes/book).
