A group of students designed an experiment to determine the impact of sucrose concentration on the weight of potato cubes. The pieces of potato were initially the same weight, shape, and size. Each potato piece was submerged into a beaker containing one of the sucrose concentrations for 30 minutes. The final weight of the potato was measured and recorded in the table. Which TWO conclusions can be correctly drawn from this data? A In the 0.4 mol/dm3 solution, the sucrose molecules moved across the semi-permeable membrane to go from a lower solute concentration (the potato) to a higher solute concentration (the sucrose solution), leading to a decrease in the weight of the potato. B In the 1 mol/dm3 solution, the water molecules moved across a semi-permeable membrane to go from a lower solute concentration (the potato) to a higher solute concentration(the sucrose solution), leading to a decrease in weight of the potato. C In the 0.8 mol/dm3 solution, the sucrose molecules moved across a semi-permeable membrane to go from a lower solute concentration (the potato) to a higher solute concentration(the sucrose solution), leading to a decrease in weight of the potato. D In the 0.2 mol/dm3 solution, the water molecules moved across a semi-permeable membrane to go from a higher solute concentration (the sucrose solution) to a lower solute concentration(the potato), leading to an increase in weight of the potato. E In the 0.6 mol/dm3 solution, the water molecules moved across a semi-permeable membrane to go from a lower solute concentration (the potato) to a higher solute concentration(the sucrose solution), leading to a decrease in weight of the potato.
