Gypsum atomic weight
WebThe most common chemical formula for gypsum is CaSO 4 •2H 2 O. Using the table below, we can determine that the atomic weight of a hydrated gypsum molecule is 172. Calculating the percentage of Ca (atomic weight 40) and S (atomic weight 32) would look like this: 40 ÷ 172 = 0.23 or 23% Ca 32 ÷ 172 = 0.186 or 18.6% S WebA property closely related to an atom’s mass number is its atomic mass. The atomic mass of a single atom is simply its total mass and is typically expressed in atomic mass units or amu. By definition, an atom of …
