A student carried out an experiment to determine how different concentrations of sucrose solution will affect osmosis. The student set up five bags of dialysis tubing with different concentrations of solutions in each one. The first one had distilled water (OM),
followed by 0,25 M, 0,5 M,0.75 M, and 1,0 M sucrose solutions. These bags were placed in distilled water for thirty minutes. The
