A sample appears in the teacher's version of the lab manual. The graph appears in the teacher's version of the lab manual. Read the molar concentration of the sucrose from the point where the curve crosses the X axis. See page 5 of the teacher's lab manual. See page 5 of the teacher's lab manual.
Water potential is zero in an open system.
Out of the bag, because the water potential is higher in the bag than outside the bag. The concentration should be read from the graph at the point where the curve crosses the X axis. The solute potential becomes more negative. The RBC will burst. Students should see the cell wall and the nucleus.
