Zinc sulfate is an inorganic compound with the formula ZnSO 4.It forms hydrates ZnSO 4 ·nH 2 O, where n can range from 0 to 7. All are colorless solids. The most common form includes water of crystallization as the heptahydrate, [4] with the formula Zn SO 4 ·7H 2 O.
Goslarite is a hydrated zinc sulfate mineral (ZnSO 4 · 7 H 2 O) which was first found in the Rammelsberg mine, Goslar, Harz, Germany.It was described in 1847. Goslarite belongs to the epsomite group which also includes epsomite (MgSO 4 · 7 H 2 O) and morenosite (NiSO 4 · 7 H 2 O).
The molar mass of atoms of an element is given by the relative atomic mass of the element multiplied by the molar mass constant, M u ≈ 1.000 000 × 10 −3 kg/mol ≈ 1 g/mol. For normal samples from Earth with typical isotope composition, the atomic weight can be approximated by the standard atomic weight [ 2 ] or the conventional atomic weight.
