Hi guys, I have a question about density.
I have found three different densities for some complexes I have made.

1: 1,51 g/cubic cm (Made from a 12 carbon chain)
2: 1,50 g/cubic cm (Made from a 14 carbon chain)
3: 1,48 g/cubic cm (Made from a 16 carbon chain)

From those results, could some conclude that the molecules interact, when the hydrophobicity increases, and the molecules pack closer per cubic centimeters?

Interact more*

Well, you know that the molecules are interacting if the volume decreases because they are taking less of a solid state. Remember, that as you increase from gas $\rightarrow$ liquid $\rightarrow$ solid, volume increases, because less molecule interaction and hence water is taking more of a solid state. That's why ice is less dense than water, and why we see ice floating on water the way we do.
