All materials have a density.
The density of materials is unchanged.

All materials - including gases - have a density !
Dissolved materials make the density of the water , more dense then before.
why do silicate materials have low electron density
Sink.
of course density"Mass/Volume"
Well if they are made of the same materials then the density should be a constant or "the same."
Density is a property; density is important in any technology to evaluate materials.
