Understanding the Molecular Weight of Manganese Sulphate Monohydrate

Manganese sulphate monohydrate, a vital compound in both industrial and agricultural applications, has the chemical formula MnSO₄·H₂O. It signifies that each molecule consists of one manganese (Mn) atom, one sulfate (SO₄) group, and one water molecule (H₂O). Understanding its molecular weight is crucial for various applications, including agriculture, chemical synthesis, and laboratory research.

Molecular Structure and Composition

To appreciate the molecular weight of manganese sulphate monohydrate, we need to break down its components. The compound is formed by the combination of manganese, sulfur, and oxygen from the sulfate group, as well as the water of crystallization. The atomic weights of these elements are as follows

- Manganese (Mn) Approximately 54.94 g/mol - Sulfur (S) Approximately 32.06 g/mol - Oxygen (O) Approximately 16.00 g/mol (for four oxygen atoms in the sulfate and one in the water) - Hydrogen (H) Approximately 1.01 g/mol (from two hydrogen atoms in the water)

Using these atomic weights, we can calculate the molecular weight of manganese sulphate monohydrate step by step

1. Manganese (Mn) 54.94 g/mol 2. Sulfate (SO₄) - Sulfur (S) 32.06 g/mol - Oxygen (O4) 4 × 16.00 g/mol = 64.00 g/mol - Total for SO₄ 32.06 + 64.00 = 96.06 g/mol 3. Water (H₂O) - Oxygen (O) 16.00 g/mol - Hydrogen (H2) 2 × 1.01 g/mol = 2.02 g/mol - Total for H₂O 16.00 + 2.02 = 18.02 g/mol

Finally, combining all these weights gives us

\[ \text{Molecular Weight of MnSO₄·H₂O} = 54.94 + 96.06 + 18.02 = 169.02 \text{ g/mol} \]

manganese sulphate monohydrate molecular weight

Thus, the molecular weight of manganese sulphate monohydrate is approximately 169.02 g/mol.
