You do an osmosis experiment in which you place 3 different bags into a beaker filled with a 3% sucrose solution. One bag is filled with a 10% sucrose solution, one is filled with a 20% sucrose solution and the third is filled with a 30% sucrose solution. After 15 minutes, you remove the bags from the beaker and measure the volume of the fluid inside. Based on what we learned in this week’s lab,which bag would you expect to have the greatest change in volume?

Question 12 options:
A)
The bag containing a 10% sucrose solution

B)
The bag containing a 20% sucrose solution

C)
The bag containing a 30% sucrose solution

D)
All bags would change by the same volume.

SaveQuestion 13 (10 points)
In an osmosis experiment you place a bag containing a 10% sucrose solution into a beaker containing a 3% sucrose solution. After 15 minutes have passed you notice a change in the volume of fluid in the bag. Assume you had placed that same bag into a beaker of distilled water (instead of the 3% sucrose solution). Would you expect to see a different result? Explain your answer. No credit will be given without an explanation.
