The apple wedges were immersed in several solutions with different concentrations of solute.
After several hours the mass and concentration of the apple wedges were measured and graphed in the dot plot. The mass was located in the y-axis and the concentration of solute was located in the x-axis.
This experiment shows the effect of osmosis.
If you look at the graph, there is a point where the change of mass of the apple wedges is zero. The concentration of the solution at this point is 0.8 mol/L
The fact that this
