A student places four identical potato cylinders into sugar solutions of different concentrations for one hour. The percentage change in mass is shown.
0.1 mol/dm³: +8%
0.3 mol/dm³: +2%
0.5 mol/dm³: −3%
0.7 mol/dm³: −9%
In which solution is the water potential closest to that of the potato cells?
0.1 mol/dm³: +8%
0.3 mol/dm³: +2%
0.5 mol/dm³: −3%
0.7 mol/dm³: −9%
In which solution is the water potential closest to that of the potato cells?
- 0.1 mol/dm³
- 0.3 mol/dm³
- 0.5 mol/dm³
- 0.7 mol/dm³
