What Is The Molar Mass Of Magnesium Sulphide?

The molar mass of magnesium sulphide (MgS) can be calculated by adding the atomic masses of one magnesium atom and one sulphur atom:

Molar mass of MgS = Atomic mass of Mg + Atomic mass of S

= 24.31 g/mol + 32.06 g/mol

= 56.37 g/mol

Therefore, the molar mass of magnesium sulphide is approximately 56.37 grams per mole.
