Divide the weight of the germanium by the change in water volume in the graduate cylinder and you will determine the density. You should come up with a density of about 5.23 g/mL. Also question is, what is the density of germanium?
5.323 g/cm³
Secondly, how is germanium extracted? Germanium is most commonly produced from sphalerite zinc ores but is also known to be extracted from fly ash coal (produced from coal power plants) and some copper ores. The oxide is then reduced with hydrogen to form germanium metal powder.
Beside this, how do you determine the density of an element?
Density of an element = ( atomic mass of the element in grams )/ ( 22.4L at STP ). How do you calculate the density of water?
- Take a known volume of the element.
- Weigh it and divide the weight by g=9.81 m/s to get the mass .
- The density is .
Where do you find germanium?
Germanium is found in germanite, argyrodite, and some zinc ores. It is also present in coal and its presence in coal insures reserves for many years.

Why germanium is not used in solar cells?
Germanium is never used by itself as a solar cell because the efficiency is much lower than silicon, a cheaper alternative.

Why Germanium is a semiconductor?
Germanium atoms have one more shell than silicon atoms, but what makes for the interesting semiconductor properties is the fact that both have four electrons in the valence shell. As a consequence, both materials readily constitute themselves as crystal lattices. The process of adding these atoms is known as doping. Is germanium a nonmetal?
