Molecular Weight Of SO2
Decoding the Composition of Sulfur Dioxide (SO2)
To understand the molecular weight of sulfur dioxide (SO2), let’s examine its atomic composition:
- Sulfur (S): Sulfur has an atomic mass of approximately 32.07 atomic mass units (amu).
- Oxygen (O): Oxygen has an atomic mass of approximately 16.00 amu.
- Sulfur dioxide (SO2) consists of one sulfur atom (S) and two oxygen atoms (O).
Calculating the Molecular Weight of SO2
To calculate the mole weight of sulfur dioxide (SO2), we sum the atomic masses of its constituent atoms according to the chemical formula:
Molecular Weight of SO2 = Atomic Mass of S + (2 × Atomic Mass of O)
Molecular Weight of SO2 = 32.07 amu + (2 × 16.00 amu)
The Molecular Weight of SO2 = 32.07 amu + 32.00 amu
Molecular Weight of SO2 ≈ 64.07 amu
Therefore, the molecular weight of sulfur dioxide (SO2) is approximately 64.07 atomic mass units (amu) or 64.07 grams per mole (g/mol).
