What granules lol?
Density usually refers to a liquid.
Solids that have a given density are measured by their mass divided by their volume. For solids like metal this is pretty easy - no air pockets.
Measure mass, measure volume.
For other compounds that form crystals (which don't really ever need a density measurement) you put them in a grad cylinder and measure the
displacement of a liquid. You can centrifuge to remove any gas in any pockets...
