Take into account that some will ionize and some will not. 0.3 M Glucose 0.3 M NaCl 0.15 M NaClIn 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. (b) Identify the osmolarity of the apple.Consider the two solutions separated by an ideal semipermeable membrane (permeable to water but impermeable to solute). Assuming complete dissociation of all the salts you can expect: a.) net water movement from side 1 to side 2 b.) net water movement from side 2 to side 1 c.) no net water movement
