A student investigates the effect of sucrose concentration on the mass of potato chips.
The table shows the results.
Table
| Concentration of sucrose solution in mol/dm3\text{mol/dm}^3mol/dm3 | Percentage change in mass |
|---|---|
| 0.0 | +14.0 |
| 0.2 | +6.0 |
| 0.4 | -2.0 |
| 0.6 | -9.0 |
| 0.8 | -15.0 |
Estimate the concentration of sucrose solution that would cause no change in the mass of the potato chips.
