10.4. Density determination of solids (hydrostatic weighing)
Density is the relationship of weight [g] : volume [cm
3
]. The weight is determined by
weighing the sample in air. The volume results from the ascending force [g] of the
sample dipped in a liquid. The density [g/cm
3
] of that liquid is known (principle of
Archimedes).
The density is determined with help of the underfloor weighing device.
Prepare the balance as follows:
Turn-over the balance
Screw-in hook for underfloor weighing (option)
Put the balance over an opening
Hook-in the sample support
Fill measuring liquid in a vessel (e.g. beaker) and temper it.

tion, density of which is known
If you selected distilled water the water temperature is input (input
range 0.0 to 99.9°).
