Water potential is the tendency of water to move from one place to another. Pumpkin cores were placed in sucrose solutions at 22°C and normal atmospheric pressure. The following data were gathered. Complete the above table. Graph the percentage change in mass. Label both the x and y axes. Using the graph, determine the molar concentration of the pumpkin cores and explain how it is related to pressure potential.
