9 wrz 2023 · Its chemical formula, CaSO4·2H2O, indicates that each unit of gypsum is composed of one calcium (Ca) atom, one sulfur (S) atom, four oxygen (O) atoms, and two water (H2O) molecules. The two water molecules are structurally bound to the calcium sulfate, giving gypsum its characteristic hydrated form.
