Formation of Magnesium Chloride The molar mass of magnesium chloride, \({\rm{MgC}}{{\rm{l}}_2}\) is \(95.211\;{\rm{g}}/{\rm{mol}}\). Preparation of Magnesium Chloride (MgCl2) Magnesium chloride is naturally found as the mineral bischofite. Hydrated magnesium chloride can be extracte...
The aqueous solution of sodium bromide is neutral. It is slightly soluble in alcohol and can react with dilute sulfuric acid to produce hydrogen bromide. Under acidic conditions, sodium bromide can be oxidized to release bromine. Sodium bromide Basic Attributes Molecular Weight: 102.894 Exact Mass...

When computing the formula mass of an ionic compound, the average masses of neutral sodium and chlorine atoms were used, rather than the masses for sodium cations and chloride anions. Even though a sodium cation has a slightly smaller mass than a sodium atom (since it is missing an electron...
Formality is the gram formula mass present per litre of a solution. If a solute’s formula mass equals its molar mass, formality equals molarity. Temperature affects a solution’s formality used for ionic substances. A formole is an ionic compound’s molarity. Formality is the moles of...
