Question

Data Table I Note: Difference in Final Volumes = Final Volume of Test Sol - Final Volume of Water

Trial	Starting Volume of Test Solution (L)	Starting Volume of Water (L)	Final Volume of Test Solution (L)	Final Volume of Water (L)	Difference in Final Volumes (L)
1	1.28	1.78	1.53	1.53	0
2	1.28	1.78	1.96	1.10	0.86

Observations and Questions

[1] Given that the final heights (and volumes) are the same for the water and test solution, what can you conclude about the amount of solutes in these two solutions? Explain your reasoning.

[2] As discussed in the Background material, water is an important biological molecule. Do you expect water to continue to flow across the semipermeable; lipid bilayer after osmotic equilibrium is reached? Why or why not?
