What is gypsum in chemistry?

Gypsum is calcium sulfate (CaSO₄). Refined gypsum in the anhydrite form (no water) is 29.4 percent calcium (Ca) and 23.5 percent sulfur (S). Usually, gypsum has water associated in the molecular structure (CaSO₄·2H2O) and is approximately 23.3 percent Ca and 18.5 percent S (plaster of paris).
