The density of germanium varies slightly depending on the temperature and crystal structure.

Here's the density of germanium at room temperature (20°C):

* 5.323 g/cm³

This value is widely accepted as the density of germanium and can be found in various reference sources, including:

* CRC Handbook of Chemistry and Physics

* NIST Chemistry WebBook

* Wikipedia

Remember, this is an approximate value, and the actual density can vary slightly based on factors mentioned earlier.
