Question

A student conducted an experiment to determine the molar concentration of solutes in chicken eggs. Eggs were soaked in vinegar to remove the shells the eggs were then placed in sucrose solutions of different concentrations. The data is shown in the table below.
Sucrose
Concentration Inltial Mass Final Mass Change in Marss Percent Change
(Molar) (g) (g) (g) in Mass
0 78.50 81.73 3.23 4.11
0.5 79.11 77.50 -1.61 -2.04
1.0 80.75 75.14 -5.61 -7.12
2.0 76.99 66.64 -10.35 -13,44
b. Using the data, determine the molar concentration of chicken egg cytoplasm and justify your answer.
c. Movement of water and nutrients is critical for the survival of plants. Using the concept of water potential, explain the role of positive and negative pressure in the transport of water and nutrients throughout a vascular plant.

Answer 1

Answer:

Explanation:

b. Based on the graph, the molar concentration is -0.32 M.

c. When water moves from areas with high water potential to areas with low, the phloem cells accumulate sugars. This results in transpiration.
