Barium sulfate, a chemical compound with the formula BaSO₄, is known for its high density and insolubility in water. It is widely used in various industries, particularly in medical imaging and manufacturing processes. Understanding the molecular weight of barium sulfate is essential for applications in both industrial and laboratory settings.
The molecular weight of barium sulfate can be calculated by summing the atomic weights of its constituent elements barium (Ba), sulfur (S), and oxygen (O). Barium has an atomic weight of approximately 137.33 g/mol, sulfur has an atomic weight of about 32.07 g/mol, and oxygen has an atomic weight of roughly 16.00 g/mol. Since barium sulfate consists of one barium atom, one sulfur atom, and four oxygen atoms, the calculation of its molecular weight proceeds as follows
1. The contribution from barium 1 × 137.33 g/mol = 137.33 g/mol 2. The contribution from sulfur 1 × 32.07 g/mol = 32.07 g/mol 3. The contribution from oxygen 4 × 16.00 g/mol = 64.00 g/mol
Adding these values together gives the molecular weight of barium sulfate
137.33 g/mol + 32.07 g/mol + 64.00 g/mol = 233.40 g/mol
Thus, the molecular weight of barium sulfate is approximately 233.40 g/mol. This figure is essential for various applications where precise measurements are critical, such as in the calibration of dosage for medical procedures or in the formulation of industrial products.
Barium sulfate’s high molecular weight contributes to its stability and makes it an ideal contrast agent in radiographic examinations. Its insolubility in water means that it can be safely ingested or injected into the body without dissolving, which helps to provide clearer images of the gastrointestinal tract during X-ray imaging.
In the industrial sector, barium sulfate is used in the production of paints, plastics, and rubber, serving not only as a filler but also enhancing the properties of the materials, such as opacity and durability. Its unique characteristics allow it to play a crucial role in improving product performance across various applications.
In conclusion, the molecular weight of barium sulfate, calculated to be approximately 233.40 g/mol, is a fundamental property that underlies its diverse applications in medical imaging and industrial manufacturing. Understanding this aspect of barium sulfate enables professionals to utilize the compound effectively, ensuring safety and efficiency in its use.
