Understanding Manganese Sulfate Monohydrate Molecular Weight and Its Importance

Manganese sulfate monohydrate, a chemical compound with the formula MnSO₄·H₂O, is an essential source of manganese, an important trace element required for human health, plant growth, and various industrial processes. This white crystalline substance plays a significant role in several domains, including agriculture, animal feeds, and the manufacturing of batteries. In this article, we will delve into the molecular weight of manganese sulfate monohydrate, its applications, and its significance in different fields.

Molecular Weight of Manganese Sulfate Monohydrate

The molecular weight of manganese sulfate monohydrate can be calculated by adding the atomic weights of its constituent elements. The components of MnSO₄·H₂O are

- Manganese (Mn) Approximately 54.94 g/mol - Sulfur (S) Approximately 32.07 g/mol - Oxygen (O) Approximately 16.00 g/mol (4 oxygen atoms in SO₄ and 1 in H₂O) - Hydrogen (H) Approximately 1.01 g/mol (2 hydrogen atoms in H₂O)

The calculation for the molecular weight is as follows

- Manganese 54.94 g/mol - Sulfate group (SO₄) 32.07 g/mol (S) + 16.00 g/mol × 4 (O) = 32.07 g/mol + 64.00 g/mol = 96.07 g/mol - Water of hydration (H₂O) 2 × 1.01 g/mol + 16.00 g/mol = 2.02 g/mol + 16.00 g/mol = 18.02 g/mol

Adding these gives the total molecular weight \[ 54.94 \, \text{g/mol (Mn)} + 96.07 \, \text{g/mol (SO}_4\text{)} + 18.02 \, \text{g/mol (H}_2\text{O)} = 169.03 \, \text{g/mol} \] Thus, the molecular weight of manganese sulfate monohydrate is approximately 169.03 g/mol.
