My results are starting to fit the expected results.
The results from experiments 5 and 6 are, however, below the expected mass dissolved. This may be because the solution was not reached saturation point.
If I have time, I will try again with 60 degrees
My CO2 on the other hand,

The results are all over the place. I need to try the experiment at 60 degrees and do another test at room temperature.
You need to compare proportion (percentage) of gas dissolved rather than absolute amounts.
