The Molar Mass of Strontium Hydroxide An Insight into Its Composition and Applications

Strontium hydroxide, with the chemical formula Sr(OH)₂, is an intriguing compound that plays a vital role in various industrial and chemical processes. Understanding its molar mass is crucial for anyone involved in chemistry, whether in a laboratory, an industrial setting, or in academia. In this article, we will explore the significance of strontium hydroxide, its molar mass, and its applications.

Composition of Strontium Hydroxide

Strontium hydroxide is a strong alkaline earth metal hydroxide, composed of strontium (Sr), oxygen (O), and hydrogen (H) atoms. To calculate the molar mass of strontium hydroxide, we need to know the atomic masses of its constituent elements.

- The atomic mass of strontium (Sr) is approximately 87.62 g/mol. - The atomic mass of oxygen (O) is about 16.00 g/mol. - The atomic mass of hydrogen (H) is roughly 1.01 g/mol.

The formula for strontium hydroxide reveals that there is one strontium atom, two oxygen atoms, and two hydrogen atoms in each formula unit. Therefore, the calculation for the molar mass of strontium hydroxide is as follows

\[ \text{Molar mass of Sr(OH)}₂ = (\text{mass of Sr}) + 2 \times (\text{mass of O}) + 2 \times (\text{mass of H}) \]

\[ \text{Molar mass of Sr(OH)}₂ = 87.62 \, g/mol + 2 \times 16.00 \, g/mol + 2 \times 1.01 \, g/mol \]

\[ = 87.62 \, g/mol + 32.00 \, g/mol + 2.02 \, g/mol \]

\[ = 121.64 \, g/mol \]
