Synonyms: Alum iron, Ferric ammonium sulfate, Iron alum, Iron (III) ammonium sulfate CAS #: 7783-83-7 EC Number: 233-382-4 Molar Mass: 482.19 g/mol Chemical Formula: (NH)Fe (SO) * 12HO Hill Formula: HNFeOS * 12 HO Grade: ACS,ISO,Reag. The molar mass of a substance, also often called molecular mass or molecular weight (although the definitions are not strictly identical, but it is only sensitive in very defined areas), is the weight of a defined amount of molecules of the substance (a mole) and is expressed in g/mol. What is the molar concentration of sulfate ion? Recently prepared samples or those that have been subjected to heat may contain a deep green-colored sulfato complex and are hygroscopic as a result.
