Figure 5.4
-Five dialysis bags,constructed from a semipermeable membrane that is 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.Figure 5.4 illustrates the change in the mass of the bags over time.Which line in the graph represents the bag that contained a 0.6 M solution at the beginning of the experiment?

Question

Quizplus · Accepted Answer

The line that represents the bag containing a 0.6 M solution at the beginning of the experiment is the one that shows no change in mass over time. This is because there is no concentration gradient for water to move in or out of the bag through the semipermeable membrane. The only line that shows no change in mass over time is line C. Therefore, C is the correct answer.
