Molar mass: 158.53 g/mol (anhydrous) 266.62 g/mol (hexahydrate) ... Strontium chloride (SrCl 2) is a salt of strontium and chloride. It is a 'typical' salt, ...
Strontium carbonate is used in the manufacturing of hard ferrite magnets. [71] [72] Strontium chloride is sometimes used in toothpastes for sensitive teeth. One popular brand includes 10% total strontium chloride hexahydrate by weight. [73] Small amounts are used in the refining of zinc to remove small amounts of lead impurities. [11]
In chemistry, the molar mass (M) (sometimes called molecular weight or formula weight, but see related quantities for usage) of a chemical compound is defined as the ratio between the mass and the amount of substance (measured in moles) of any sample of the compound. [1] The molar mass is a bulk, not molecular, property of a substance.
Molar mass: 211.630 g/mol (anhydrous) ... Strontium sulfate Strontium chloride: Other cations. ... Strontium nitrate is an inorganic compound composed of the elements ...
Molar mass: 121.63 g/mol (anhydrous) 139.65 g/mol (monohydrate) ... It may be used as a source of strontium ions when the chlorine from strontium chloride is undesirable.
Historically, the mole was defined as the amount of substance in 12 grams of the carbon-12 isotope.As a consequence, the mass of one mole of a chemical compound, in grams, is numerically equal (for all practical purposes) to the mass of one molecule or formula unit of the compound, in daltons, and the molar mass of an isotope in grams per mole is approximately equal to the mass number ...
The equivalent weight of an element is the mass which combines with or displaces 1.008 gram of hydrogen or 8.0 grams of oxygen or 35.5 grams of chlorine. The equivalent weight of an element is the mass of a mole of the element divided by the element's valence. That is, in grams, the atomic weight of the element divided by the usual valence. [2]
The alkaline earth metal strontium (38 Sr) has four stable, naturally occurring isotopes: 84 Sr (0.56%), 86 Sr (9.86%), 87 Sr (7.0%) and 88 Sr (82.58%). Its standard atomic weight is 87.62(1). Only 87 Sr is radiogenic ; it is produced by decay from the radioactive alkali metal 87 Rb , which has a half-life of 4.88 × 10 10 years (i.e. more than ...
