Chemical formula for sphalerite.

Troilite has a chemical composition of FeS, while pyrrhotite's chemical composition is Fe (1-x) S. Pyrrhotite is deficient in iron because some of the iron sites in its crystal lattice are vacant (empty). That is why the iron in the formula has a subscript of 1-x. The value of "X" in the chemical formula of pyrrhotite can range between 1 and 0.17.
