Potassium Permanganate (KMnO4): A Versatile Chemical Compound

Potassium permanganate, represented by the chemical formula KMnO4, is a powerful and versatile chemical compound that plays a significant role in various scientific, industrial, and medical applications. Its striking purple color and powerful oxidizing properties have made it a staple in laboratories and industries around the world.

Breaking Down the Molecular Weight of KMnO4

The molecular weight of a compound is determined by summing the atomic weights of all the atoms present in one molecule of that compound. To calculate the molecular weight of KMnO4, we must consider the atomic weights of its constituent elements:

1. Potassium (K): The atomic weight of potassium is approximately 39.10 g/mol.
2. Manganese (Mn): Manganese has an atomic weight of roughly 54.94 g/mol.
3. Oxygen (O): The atomic weight of oxygen is around 16.00 g/mol.

Now, let’s perform the calculations:

Molecular Weight of KMnO4 = (Atomic Weight of K) + (Atomic Weight of Mn) + (4 * Atomic Weight of O)

Molecular Weight of KMnO4 = (39.10 g/mol) + (54.94 g/mol) + (4 * 16.00 g/mol)

Molecular Weight of KMnO4 = 39.10 g/mol + 54.94 g/mol + 64.00 g/mol

Molecular Weight of KMnO4 ≈ 158.04 g/mol

Thus, the molecular weight of potassium permanganate (KMnO4) is approximately 158.04 grams per mole.
