Two identical model cells are made from partially permeable tubing. Each model cell contains the same volume of the same solution. The dissolved solute cannot cross the tubing.
The model cells are placed in different surrounding solutions for 20 minutes. The results are shown in the table.
| Model cell | Surrounding solution | Initial mass (g) | Mass after 20 minutes (g) |
|---|---|---|---|
| A | A | 8.00 | 8.00 |
| B | B | 8.00 | 7.36 |
Model cell A is removed from solution A. Its surface is dried and it is placed in a fresh sample of solution B.
State what will happen to the mass of model cell A during the next few minutes.
Explain your answer using the results in the table.
