1. What Is The Molecular Weight Of Magnesium Sulfide?

The molecular weight of magnesium sulfide (MgS) is approximately 56.38 g/mol. This is calculated by adding the atomic weights of one magnesium atom (24.31 g/mol) and one sulfur atom (32.07 g/mol) together, since there is only one atom of each element in the formula unit of MgS.
