A student investigated the effect of different concentrations of sodium chloride solution on the mass of courgette cylinders. Each cylinder was fully immersed in its respective solution for 60 minutes.
| Sodium chloride concentration (mol/dm3mol/dm^3mol/dm3) | Initial mass (g) | Final mass (g) |
|---|---|---|
| 0.0 (Distilled water) | 2.45 | 2.68 |
| 0.2 | 2.46 | 2.51 |
| 0.8 | 2.44 | 2.18 |
Explain the change in mass of the courgette cylinder in the 0.8 mol/dm3 mol/dm^3\,mol/dm3 sodium chloride solution.
