The empirical formula for pyrite is FeS2.
HOW TO CALCULATE EMPIRICAL FORMULA:
- The empirical formula represents the simplest whole number ratio of constituents element of a compound. The empirical formula of pyrite can be calculated as follows:
46.5 mass % Fe = 46.5g of Fe
53.5 mass % S = 53.5g of S
- Next, we divide each element's mass value by its molar mass
Fe = 46.5g ÷ 56g/mol = 0.83mol
S = 53.5g ÷ 32g/mol = 1.67mol
- Next, we divide each mole value by the smallest (0.83mol)
Fe = 0.83mol ÷ 0.83 = 1
S = 1.67mol ÷ 0.83 = 2.014
Approximately, the ratio of Fe to S is 1:2. Therefore, the empirical formula of pyrite is FeS2.

The organic compounds that are divided into two types, simple and complex, are called carbohydrates.
Carbohydrates are diveded into twy types: simple and complex (starches, fiber, glycogen).
Simple carbohydrates are made of one (monosaccaharides) or two sugar units.
Complex carbohydrates are made up of many sugar units.
For example, glucose (C₆H₁₂O₆) is a simple carbohydrate.
Glucose is chemical compound composed of six carbon atoms, twelve hydrogen atoms and six oxygen atoms.
Starch is a polymeric carbohydrate consisting of a large number of glucose units bonded by glycosidic bond. Starch is a white, tasteless and odorless powder that is insoluble in cold water or alcohol.
