Question
- In an investigation of osmosis, apple cores were submerged in different molarity solutions to determine the unknown osmolarity of the apple. To determine the molarity five uniform apple cores were massed before submerging them in different molarity solutions. After 24 hours the apple cores were massed again. Then the percent change in mass was determined for the five uniform apple cores in each molarity solution.
c) Describe the environmental conditions taking place in each of the six solutions with the apples

Expert Solution
Step 1
| Molarity of the solution | |
| 0 | In this case, water from the solution enters the apple cores due to endosmosis because the solution is hypotonic (less concentrated) compared to apple core. Therefore there is increase in weight of the apple cores. |
| 0.2 | In this case, water from the solution enters the apple cores due to endosmosis because the solution is hypotonic (less concentrated) compared to apple core. Therefore there is increase in weight of the apple cores. |
| 0.4 | In this case, water goes out from the apple core into the solution due to exosmosis because the solution is hypertonic (more concentrated) compared to the apple core. Therefore there is decrease in the weight of apple cores. |
