What is Barium Sulfate (BaSO4)?

Barium sulfate is a chemical compound with the formula BaSO4. It is a white crystalline solid that is insoluble in water. This compound is commonly used as a radiocontrast agent in medical imaging, as a filler in paints and plastics, and in the production of paper and textiles. Its chemical properties make it a versatile material in various applications.

Calculating the Molar Mass of BaSO4

The molar mass of a compound is the sum of the atomic masses of all the atoms in its chemical formula. To calculate the molar mass of BaSO4, we need to know the atomic masses of barium (Ba), sulfur (S), and oxygen (O). The atomic masses are approximately:

Barium (Ba): 137.33 g/mol
Sulfur (S): 32.07 g/mol
Oxygen (O): 16.00 g/mol

Barium sulfate has one barium atom, one sulfur atom, and four oxygen atoms. Therefore, the molar mass of BaSO4 is calculated as follows:

Molar Mass of BaSO4 = (1 × 137.33) + (1 × 32.07) + (4 × 16.00)

Let’s break down the calculation:

Barium: 1 × 137.33 = 137.33 g/mol
Sulfur: 1 × 32.07 = 32.07 g/mol
Oxygen: 4 × 16.00 = 64.00 g/mol

Adding these values together, we get:

137.33 + 32.07 + 64.00 = 233.40 g/mol

Therefore, the molar mass of BaSO4 is 233.40 g/mol.
