No. of water molecules in Epson salt?
- Epsom salt is magnesium sulphate (MgSO4⋅7H2O).
- In this compound, six water molecules are directly coordinated with Mg2+ ions.
- Hence, it can be represented as [Mg(H2O)6](H2O)(SO4).

- Hematite and magnetite are by far the most common types of ore.
- Pure magnetite contains 72.4 percent iron, hematite 69.9 percent, limonite 59.8 percent, and siderite 48.2 percent, but, since these minerals never occur alone, the metal content of real ores is lower.
