manganese sulfate molecular weight

Manganese sulfate, a chemical compound with the formula MnSO₄, is widely utilized in various industrial and agricultural applications. Understanding its molecular weight is crucial for researchers and industry professionals engaged in chemical formulations and reactions, as this property affects the compound’s behavior and efficacy in various processes.

The molecular weight of manganese sulfate can be calculated by summing the atomic weights of its constituent elements manganese (Mn), sulfur (S), and oxygen (O). The atomic weight of manganese is approximately 54.94 g/mol, sulfur is about 32.07 g/mol, and oxygen has an atomic weight of roughly 16.00 g/mol. Manganese sulfate typically exists in two forms anhydrous (MnSO₄) and heptahydrate (MnSO₄·7H₂O).

For the anhydrous form, the calculation of the molecular weight is as follows

- Manganese (Mn) 54.94 g/mol - Sulfur (S) 32.07 g/mol - Oxygen (O) in SO₄ 4 × 16.00 g/mol = 64.00 g/mol

Adding these together gives 54.94 g/mol (Mn) + 32.07 g/mol (S) + 64.00 g/mol (O) = 151.01 g/mol.

Thus, the molecular weight of anhydrous manganese sulfate is approximately 151.01 g/mol.

For the heptahydrate form, the contribution from water must also be added. Each water molecule (H₂O) has a molecular weight of about 18.02 g/mol, and since there are seven water molecules, their total contribution is

7 × 18.02 g/mol = 126.14 g/mol.

Adding this to the anhydrous form’s weight gives 151.01 g/mol (anhydrous) + 126.14 g/mol (water) = 277.15 g/mol.

Thus, the molecular weight of manganese sulfate heptahydrate is approximately 277.15 g/mol.

Manganese sulfate is crucial in agriculture as a micronutrient for plants. It plays a significant role in chlorophyll production and overall plant health. Furthermore, it is employed in the manufacturing of fertilizers, animal feed, and various chemical processes. Understanding its molecular weight enables precise applications and formulations, ensuring that sufficient manganese is provided to support plant growth and development. As an essential element, manganese's role cannot be overstated, making manganese sulfate an important compound in both agricultural and industrial contexts.
