An experiment to calculate the water potential of potato cells was performed using the following protocol:
- Dice potato into 1cm3 cubes.
- Add potato cubes to 6 test tubes, each containing solution with a different sucrose concentration.
- Wait 12 hours.
- Weigh the cubes from each test tube and plot a graph.
The mean mass of the potato cubes was 2.50 g before being added to the solution, and the graph shows the masses of the potato cubes after the experiment.
Which concentration of sucrose matches the water potential of the potato cells?
0.00 mol dm-3
0.12 mol dm-3
0.31 mol dm-3
0.66 mol dm-3
