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...
The invention discloses a formula of a culturing agent for producing DNA from Crypthecodinium cohnii. The formula comprises, by mass, 7.2-8.8 parts of peptone, 1.8-2.2 parts of sodium nitrate, 16-22 parts of glucose, 4.5-5.5 parts of sodium acetate, 5.4-6.6 parts of sodium chloride, ...
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...
