A student peeled the skins from grapes, exposing cells with membranes that are only permeable to water and small diffusible solutes. The student measured the mass of the peeled grapes. The student then placed each peeled grape into one of five solutions. After 24 hours, the student removed the peeled grapes from the solutions, measured their final mass, and calculated the percent change in mass (Table 1). TABLE 1. PERCENT CHANGE IN MASS OF PEELED GRAPES IN SOLUTIONS Concentration of Solution Solution Percent Change in Mass (weight/volume) Distilled water 0% 13.48% Naci 20% -23.39% Tap water 0.8% 9.46% Grape juice 2.1% 2.8% Grape soda 13% -15.00% In a second experiment (Table 2), the student placed a peeled grape into a solution containing both small diffusible solutes and solutes to which the membrane is impermeable (nondiffusible solutes).
