Potato cylinders of equal size were placed in sugar solutions of different concentrations for 1 hour. The table shows the results.
| Sugar concentration / mol dm⁻³ | Initial mass / g | Final mass / g |
| 0.1 | 2.40 | 2.65 |
| 0.3 | 2.35 | 2.37 |
| 0.5 | 2.50 | 2.40 |
| 0.7 | 2.45 | 2.20 |
In which sugar concentration is the water potential closest to that of the potato cells?
