Weight gain of potato section in sucrose concentration
This is my first post here. I'm slightly stuck with the lesson I'm at in Biology, and wondering if you could help me. Here goes.
If my 10g piece of potato has an approx. sucrose concentration of 1.65%, and it is put in a sucrose concentration of 0.1%, (or 2.2% or 4.*%) how do I calculate how much weight it gains? I have the following table to work with, but I'm not sure how much help that is, because there does not seem to be any correlation between the weight gain and the sucrose concentration, due to turgor pressure I suppose.
Beaker Concentration of Sucrose (%) Weight of Potato Cube after 24 Hrs (grams) Percent Change in Mass (%)
1 0.0 13.4 34
2 0.5 12.5 25
3 1.0 11.2 12
4 1.5 10.3 3
5 2.0 9.2 -8
6 2.5 8.5 -15
7 3.0 8.0 -20
8 3.5 7.7 -23
9 4.0 7.5 -25
10 4.5 7.4 -26
Thanks so much!
