Question

Question 9 A group of students are conducting an experimentSince potatoes contain both sugar and water, the students use them in the experiment. The students cut six equal cubes of potato and weigh them. They place the six cubes into six different beakers containing different concentrations of sugar solutions, then weigh each potato cube after 24 hours and calculate the percent change in massThe graph below shows the result of their experiment. Percent Change Mass of Potato Cores Versus Sucrose Solution Concentration 25 15 Change in Potato Core Mass -10 15 cube 4 cube 5 02 04 08 Concentration of Sucrose Solution Which of the statements below is a valid conclusion about this experiment ? The the concentration of sugar, the more the water concentration will be at equilibrium The lower the concentration of sugar , the less likely the potato will gain mass The the concentration of sugar , the more the potato gain The lower the concentration of sugar, the more likely the potato will gain mass

Answer 1

Based on the context of your experiment with potato cubes placed in varying concentrations of sugar solutions, the relevant conclusion can be derived from the relationship between solute concentration (sugar) and water movement due to osmosis.

The valid conclusion about this experiment is:

The lower the concentration of sugar, the more likely the potato will gain mass.

This conclusion is based on the principles of osmosis, where water moves from an area of lower solute concentration (higher water concentration) to an area of higher solute concentration (lower water concentration) in an attempt to reach equilibrium. In lower concentrations of sugar solution, there is a higher water potential outside the potato, leading to water entering the potato and resulting in an increase in mass.

The other statements do not accurately reflect the principles of osmosis as observed in the experiment.
