Question

question 3
a group of students are conducting an experiment. since 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 mass. the graph below shows the result of their experiment.
percent change in mass of potato cores versus sucrose solution concentration
which of the statements below is a valid conclusion about this experiment?
o a the lower the concentration of sugar, the less likely the potato will gain mass.
o b the higher the concentration of sugar, the more likely the potato will gain mass.
o c the higher the concentration of sugar, the more likely the water concentration will be at equilibrium.
o d the lower the concentration of sugar, the more likely the potato will gain mass.

Explanation:

The experiment involves potato cubes in sucrose solutions, measuring mass change due to osmosis. Water moves from low to high solute concentration. The graph shows: lower sucrose concentration correlates with positive mass change (water gain), higher concentration with negative change (water loss).

Answer:

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