Question
**Assessing a Student's Hypothesis on Solute Concentration in Grape Juice** A student hypothesizes that the solute concentration of grape juice is higher than the solute concentration of the actual grape because the grape juice has added sugar. Based on the data in Table 1, which of the following best evaluates the student’s hypothesis? ### TABLE 1. PERCENT CHANGE IN MASS OF PEELED GRAPES IN SOLUTIONS | Solution | Concentration of Solution (weight/volume) | Percent Change in Mass | |-------------------|------------------------------------------|------------------------| | Distilled water | 0% | 13.48% | | NaCl | 20% | -23.39% | | Tap water | 0.8% | 9.46% | | Grape juice | 2.1% | 2.8% | | Grape soda | 13% | -15.00% | ### Evaluation Options: 1. The hypothesis is supported because the mass of the grape decreased in the grape juice. 2. The hypothesis is not supported because the mass of the grape increased in the grape juice. 3. The hypothesis is not supported because the grape was isotonic to the grape juice. 4. The hypothesis is supported because the grape juice has a greater solute potential than the grape has. ### Graph/Diagram Explanation: The table above shows the impact on the mass of peeled grapes when placed in various solutions with different concentrations. The 'Percent Change in Mass' column indicates whether the grapes gained or lost mass in each solution. For example: - **Distilled Water (0% concentration)**: Grapes in distilled water experienced a 13.48% increase in mass. - **NaCl (20% concentration)**: Grapes in this saline solution saw a significant mass decrease of 23.39%. - **Tap Water (0.8% concentration)**: Grapes placed here increased in mass by 9.46%. - **Grape Juice (2.1% concentration)**: There was a minor increase in mass by 2.8%. - **Grape Soda (13% concentration)**: Grapes in grape soda experienced a 15% decrease in mass. ### Correct Assessment: The hypothesis is **not supported** because of the minimal change in mass when grapes were placed in grape juice, suggesting the
