Do you know a database which lists the molecular volumes of organic solvents?
Thank you so much.
Take the molar mass and divide it by the density (in g/L or mg/mL)
This will give you the solvent volume in litres, per mole of solvent.
If you wanted to you could then divide by Avogadro's number to get the volume of a molecule in L and multiple that by 10^27 to convert that into cubic Angstroms per molecule.
But that would be a state dependent physical measure of the applied real world volume of the pure solvent, rather than a specific measure of molecular dimensions.
There are also tools you could use to compute the molecular volume, which is primarily used a measure for membrane permeability and passive diffusion in drug design.
What application or use do you have for the molecular volumes in this case?
Some might work

Thank to everybody for the answers, at least I have performed the calculus proposed by Sun.
I have need to know the values in order to establish the intensity of the Van der Waals interactions between the solvent molecules and a molecule that I have in solution .I think that is too correct if I utilize the Van der Waals surface, in fact; I have computed it utilizing PyMol.
What do you think about this ?
If you are looking for the Van der Waals interactions then yes, you want the solvent available surface area rather than the volume.
