A potato cylinder is placed in a concentrated sugar solution. What happens to its mass?
Answer and explanation
Correct answer: C. It decreases, because water leaves the cells by osmosis
- Step 1: The solution outside has a lower water concentration than the cells. Step 2. Water therefore moves out of the potato by osmosis, so mass falls. Answer: It decreases, because water leaves the cells by osmosis. Why not the others: The cells would gain mass only in a more dilute solution.
