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

  1. 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.
