These are my final results for my CO2 !!

The results are fairly spread out, however, they do generally follow the expected trend. Graphing the average volume dissolved could make this clearer.

With the exception of the results for 50 degrees, the results seem to be sticking to the trend pretty well.
Tomorrow, I may do a final repeat for 50 degrees but apart from that, I am finished my experimentation. :)
