9. What Is The Density Of Magnesium Sulfide?

The density of magnesium sulfide (MgS) varies depending on its crystal structure and purity. The theoretical density of MgS is 2.71 g/cm³, based on the compound's atomic weight and volume. However, the actual density of MgS can be lower due to the presence of defects or impurities.

Experimental measurements of MgS density have been reported in literature, with values ranging from 2.4 to 2.8 g/cm³ depending on the sample preparation and measurement method used. For example, one study measured the density of polycrystalline MgS to be 2.68 g/cm³ using a helium pycnometer, while another study reported a density of 2.76 g/cm³ for single crystal MgS using X-ray diffraction.

In summary, the density of magnesium sulfide is approximately 2.71 g/cm³ in theory, but actual measured values can vary between 2.4 and 2.8 g/cm³ depending on various factors.
