Density determination (Hydrostatic weighing)

Density is the relationship of weight [g] : volume [cm
weighing the sample in air. The volume results from the ascending force [g] of the
sample dipped in a liquid. The density [g/cm
Archimedes).
The density is determined with help of the underfloor weighing device.
