If we have five dialysis bags being formed from a semi-permeable membrane which is impermeable to sucrose, they may be saturated with different concentrations of the sucrose with each of these bags being positioned in different beakers that have an initial amount of 0.6 M of a sucrose solution.

At ten minute intervals, the bags were massed and the weight was calculated to look for changes in the level of concentration. In this situation, the bag with the lowest initial concentration of sucrose is be the one that has its mass reducing over time and that is E.

The attached image confirms our answer as from the graph, option E shows the lowest initial concentration of sucrose.
