1. You could look up lists of known densities for a match.\n\n2. If not found, the density can give you a clue concerning the nature (metallic, organic, etc) or category.

It's kida hard to explain comprehensively in 1000 characters or less, so the next best thing I can do right now is put a link to a website that explains the  diferences in layman's term in the source below.\nHope that helps you out.

Examples of extensive properties:\n\nMass \nVolume \nEntropy \nEnergy \nElectrical resistance \nTexture \nHeat \n\nAn extensive property of a system depends on the system size or the amount of material in the system. An intensive property on the other hand is a physical property of the system that does not depend on the system size or the amount of material in the system.\n\nHopefully that gives you and idea and you found what you were looking for.
