In an osmosis experiment, identical potato strips are placed in three sugar solutions: P (0.10 mol dm⁻³), Q (0.30 mol dm⁻³) and R (0.50 mol dm⁻³). After 30 minutes, the strip in Q shows no change in length. What can be concluded about the concentration of the cell sap in the potato cells?
- 0.30 mol dm⁻³
- 0.10 mol dm⁻³
- 0.20 mol dm⁻³
- 0.50 mol dm⁻³
