Students performed a laboratory experiment to determine the molar concentration of red potatoes. They cut cubes from a whole red potato and massed them. They placed the cubes into various sucrose solutions, whose molar concentrations are shown above. The students then removed the potato cubes from the solutions twenty-four hours later and massed them again. They calculated the percent change for the potatoes in the various solutions. All of the data is displayed above. What is the approximate molar concentration of the red potatoes used in this experiment?
A) The red potatoes have approximately a 0.40 M solute concentration because is the treatment with the smallest percent change.
B) The red potatoes have approximately a 0.0 M solute concentrations because they have no sucrose component, only starch components.
C) The red potatoes have approximately a 0.37 M solute concentration because this is where the potatoes would neither gain nor lose mass.
D) The red potatoes have approximately a 1.0 M solute concentration because this is the treatment where the potatoes lost the greatest percentage.
