There is no change of mass at a sucrose concentration of 0.23M, shown by where the line of best fit crosses the x axis, at this point it is isotonic. From this, the water potential of the potato was approximately -680kPa.

I have put some general comments here.

It's not quite true to say that as sucrose concentration increased percentage change in mass decreased. Percentage change can be positive or negative, so the percentage change changed from being a positive change, an increase in mass of the potato to a negative change a decrease in mass of potato, but the changes were quite large at concentrations of sucrose very hypertonic or very hypotonic to the concentration of the potato tissue. It's not wrong.. you just have to phrase it carefully.
