A student investigated osmosis in carrot tissue. The student placed identical carrot cylinders in sucrose solutions for the same length of time.
The table shows two of the results.
| Concentration of sucrose solution in mol/dm³ | Mean percentage change in mass |
|---|---|
| 0.30 | −1.8% |
| 0.40 | −5.6% |
The student places another identical carrot cylinder in a sucrose solution with a concentration of 0.35 mol/dm³.
Explain whether the mass of this carrot cylinder is expected to increase or decrease.
