  1. In an investigation of osmosis, apple cores were submerged in different molarity solutions to determine the unknown osmolarity of the apple. To determine the molarity five uniform apple cores were massed before submerging them in different molarity solutions. After 24 hours the apple cores were massed again. Then the percent change in mass was determined for the five uniform apple cores in each molarity solution.

In an investigation of osmosis, apple cores were submerged in
different molarity solutions to determine the unknown osmolarity of the
apple. To determine the molarity five uniform apple cores were
massed before submerging them in different molarity solutions. After
24 hours the apple cores were massed again. Then the percent
change in mass was determined for the five uniform apple cores in
each molarity solution.
