Sure, but box shape doesn't mean anything. Box volume is what is important. I
can make a cubic box with 1-nm edges and I can make a box with 100000-nm edges;
they're both cubic but that fact tells you nothing about the volume.

Well, it's one molecule, not 1 mol.

I have no idea what this means. It's absolutely trivial to convert between a
number of particles (in this case, 1) and a volume in nm^3 to a concentration.
It's simple unit transformation - consult any basic chemistry textbook.
