I have not done any filtering yet with the resveratrol mixture. It's still on the magnetic stirrer. I'm thinking I should filter it with the same 0.22 μm filter I use on my c60 solution. I happen to have some pure olive oil on hand that I've already run through that filter size. So I figure if I can accurately get some equal volumes, then some weight measurements might give an indication of how much is dissolved. But the milligram scale I have maxes out at 50 grams so I'm limited on the quantity I can deal with. I figure I might get some fairly consistent small volumes to work with using a medicine dropper. I'll play around with a laser pointer before and after filtering and see if I notice any deflection differences. But I want to keep my resveratrol mixing at least another week.
I don't think you'll be able to get an accurate value for resveratrol solubility in olive oil this way. When a compound dissolves in a solvent, it can affect the density of the solvent in non-obvious ways. The volume could either go up, down, or stay roughly the same. You'd probably have better luck weighing the resveratrol that ends up on the filter. You'd need to wash off the olive oil with something that wouldn't dissolve the resveratrol. I'm not sure what would be best there.. An alkane, maybe, like hexane or heptane? It might be enough to just estimate the weight, if there isn't much there.
The point of doing the molar calculation was that if the previous numbers are the max, then the resveratrol is at 1/3 molar concentration as the c60, which means it is probably bonding to a different part of the olive oil. Perhaps it is attracted to the glycerin, and the C60 is attracted to the fatty acid part?
Resveratrol doesn't bond to olive oil. It's just an ordinary solution, where the resveratrol molecules are floating around in the olive oil. It's probably attracted to both parts of the triglyceride. C60, on the other hand, forms a chemical bond with the fatty acid chain.
