Question by Wolf Mike: What is the relationship between solubility and density of a chemical?
I’m trying to find the density for a few chemicals.

But first tell me what the relationship between solubility and density for a compound is.

What is the relationship between solubility and density of a chemical? — There isn’t one. There is no direct or inverse relationship between the solubility of a compound and its density.

Peanut says, “Density is a unit of mass divided by a unit volume; whereas, solubility volume used to consume (divide) the mass. Or dissolve it.”

Density is indeed the mass of the substance divided by its volume, but solubility is not the volume of a substance divided by its mass. The volume is the volume of the solvent, which is not the same as the mass, which is the solute. Besides, we usually use the mass of solvent in specifying solubility as in “grams of solute per 100 grams of solvent.”

So no, they are not comparing the same volumes and density and solubility are not the reciprocals of each other.
