Five dialysis bags, constructed of a type of membrane that is permeable to water and impermeable to sucrose, were filled with various concentrations of sucrose and then placed in separate beakers containing an initial concentration of 0.6 M sucrose solution. At 10-minute intervals, the bags were massed (weighed) , and the percent change in mass of each bag was graphed.
Which line or lines in the graph represent(s) bags that contain a solution that is hypertonic at 50 minutes?
