5.6.2 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. 5.5.1.
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:

How to carry out see chap. 5.5.1. In the weighing „Sample in auxiliary liquid“ do
not place the sample upon, but under the sifting bowl, see fig. 4, chap. 5.1.3.
