strontium chloride molar mass

Strontium chloride, with the chemical formula SrCl₂, is an inorganic compound composed of strontium and chlorine. It presents a white crystalline solid at room temperature and is highly soluble in water. Understanding its molar mass is crucial for a variety of applications in chemistry and materials science, particularly in stoichiometric calculations, preparation of solutions, and during chemical reactions involving strontium ions.

The molar mass of strontium chloride can be calculated by summing the molar masses of its constituent atoms. Strontium (Sr), positioned in group 2 of the periodic table, has an atomic mass of approximately 87.62 g/mol, while chlorine (Cl), found in group 17, has an atomic mass of about 35.45 g/mol. Since strontium chloride contains one strontium atom and two chlorine atoms, the molar mass can be calculated as follows

\[ \text{Molar Mass of SrCl}_2 = 1 \times \text{Molar Mass of Sr} + 2 \times \text{Molar Mass of Cl} \]

Substituting the values, we have

strontium chloride molar mass

\[ \text{Molar Mass of SrCl}_2 = 1 \times 87.62 \, \text{g/mol} + 2 \times 35.45 \, \text{g/mol} \] \[ = 87.62 \, \text{g/mol} + 70.90 \, \text{g/mol} \] \[ = 158.52 \, \text{g/mol} \]

This means that the molar mass of strontium chloride is approximately 158.52 g/mol. This value is critical for laboratory work, enabling chemists to calculate the precise amounts of strontium chloride needed to prepare solutions of desired concentrations or to carry out reactions involving strontium ions.

In industry, strontium chloride is utilized in various applications including fireworks, where it produces vivid red colors. It is also used in the production of ceramic materials and in the fields of medicine and optics. Furthermore, because of its property to absorb moisture from the atmosphere, anhydrous strontium chloride is typically used in desiccant applications.

In conclusion, the molar mass of strontium chloride, 158.52 g/mol, is not only fundamental in chemical calculations but also highlights the compound's relevance in both industrial and scientific contexts. Understanding its properties and applications continues to be essential for advancements in fields like materials science, environmental chemistry, and manufacturing processes.
