I am just a little confused about this.  I know that caffeine is soluble in acetone, as I have read from various sources, but I cannot figure out why/how much acetone is needed to completely dissolve a certain mass of caffeine.  Could anyone offer me some resources to look at in order to try and figure out how exact numbers could be discovered and why that is the case?  I understand water solubility but am confused about solubility in different solvents and how to discern much solute/solvent would be necessary.  Thanks for any info!

There are various handbooks that may contain this information, check them in library. CRC Handbook, perhaps Knovel Interational Critical Tables (or whatever is their exact name).
