Question

Zucchini cores placed in sucrose solutions at 27oC resulted in the following percent changes after 24 hours:
% change in mass [Sucrose]
20 distilled water
10 0.2 M
-3 0.4 M
-17 0.6 M
-25 0.8 M
-30 1.0 M

Graph the results and find the molar concentration of solutes within the zucchini cells. Calculate the solute potential of the sucrose solution in which the mass of the zucchini cores does not change. Calculate the water potential of the solutes within the zucchini cores.
