A student peeled the skins from grapes, exposing cells with membranes that are only permeable to water. The student measured the mass of the peeled grapes. The student then placed each peeled grape into one o 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 Solution Seawater Concentration of Solution Percent Change in Mass (weight/volume) 3.5% 11% 18% 1.3% Grape soda CaCl₂ Grape juice Identify one solution that is hypertonic to the grape. Justify your choice. 1.8% -11.4% -21.5% -0.5%
