Which line represents the bag with the lowest initial concentration of sucrose? Five dialysis bags, constructed from a semi-permeable 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.

The correct answer is option E Option E represents the bag with the lowest initial concentration of sucrose. If the five bags were constructed from a semi permeable membrane is IMPERMABLE to sucrose and placed each dialysis bag is placed in separate beakers that contain an initial concentration of 0.6 M sucrose solution. The dialysis bag with the lowest concentration of sucrose will decrease in mass over time.

At ten minute intervals, the weight of each bag will remain unchanged in the percentage of concentration. This is because the bag is impermeable to sucrose. Therefore, the bag with the initial lowest concentration of sucrose would be the one that experience decrease in mass over time. From the graph, we can tell that option E has the lowest initial concentration of sucrose.

It is common for dialysis bags or dialysis tubing to be used to allow for smooth flowing of molecules when dealing with a fluid. These bags are usually measured to make sure that the patient has enough in the bag to accomplish the goal at hand.

If there were five dialysis bags constructed from a semi-permeable membrane that is impermeable to sucrose, they may be filled with various concentrations of the sucrose. Then each of these bags was place in separate beakers containing an initial concentration of 0.6 M of a sucrose solution.

At ten minute intervals, the bags were massed and weighed to see the change in the percent of concentration. In this case, the bag with the lowest initial concentration of sucrose would be the one whose mass decreases over time.
