Difference Between Density and Concentration l Density vs

Sep 17, 2011 · The key difference between density and concentration is that the density of a substance depends only on the amount of matter within a given volume whereas the concentration depends on the amount of matter and what compound is in there, as well. Furthermore, density can be homogeneous or heterogeneous depending on
