Water potential in potato cells was determined in the following manner. The initial masses of six groups of potato cores were
measured. The potato cores were placed in sucrose solutions of various molarities. The masses of the cores were measured again
after 24 hours. Percent changes in mass were calculated. The results are shown in the data table.
Question:
-Determine the apparent molar concentration (osmolarity of the potato core cells.
-Determine where the solution was hypertonic.
