I have been searching all over for the CORRECT molecular weight of the fullerene C60, also called the buckministerfullerene. The weights I see listed do not account for the HYDROGENS!!!!! People assume it's just C60, when actually there are hydrogens sticking out from the cage. I've searched in the Sigma-Aldrich chemical catalog, but to my surprise they have it listed wrong too (720.66 g/mol). Does anyone know the correct molecular weight for the fullerene? Edit: Nevermind. It's C60H60.
