Its chemical composition is Magnesium Aluminum Silicate (Mg 2 Al 3 O).For example, the hydrous mineral Opal has a loosely defined composition with an inconsistent amount of water in its structure, thus its chemical formula is written as "SiO 2 · nH 2 O". Some minerals, such as Torbernite, have a varying amount of water within fixed limits. The chemical formula for Torbernite is "Cu(UO 2)(PO 4) 2 · 8-12H 2 O".
