5.4.3 Determine density of floating solid bodies (d <1 g/cm
3
):
At solid material with density less than 1 g/cm
3
, a density determination with two
different methods is possible.
Method 1:
How to carry out see chap. 5.3.2.
As aid liquid is used a liquid with less density than that of the solid material, e.g.
ethanol approx. 0.8 g/cm
3
.
This method should be applied when the density of the solid is just slightly different
from that of the distilled water.
Using ethanol is not recommended, when the solid material is being attacked.
When working with ethanol, you must observe the applicable safety regulations.
Method 2:

Make sure that the balance is in the mode for density determination of solid
material (see chap. 5.3.1).
Set balance to zero.

Place sample of solid material in the upper sample dish, see fig. 3, chap. 5.1.3.
The weight of the „sample in air“ is displayed.

Wait for stability display ( ), then press .

Place the solid material entirely under the lower sifting bowl, see fig. 3, chap.
5.1.3.
For this purpose remove the immersion basket and for re-immerging sink the
sample in the liquid.
Or if possible place the sample using pincers or alike directly under the sifting
bowl.
The weighing balance will first determine then display the sample’s density.

If you connect an optional printer you can print the result.
