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 conetrations 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?
