The Composition of Fe2O3: A Molecular Journey
Fe2O3 is composed of two iron atoms (Fe) and three oxygen atoms (O), hence its name, iron(III) oxide. This compound forms a crystalline structure with a specific arrangement of atoms, which gives it its unique characteristics.
The iron atoms in Fe2O3 exist in their +3 oxidation state, making them ‘ferric’ ions (Fe^3+). These ions are surrounded by oxygen atoms in a specific geometric pattern, forming a robust molecular network. This structure contributes to the compound’s stability and its fascinating magnetic properties.
Determining Molar Mass: A Step-by-Step Guide
Calculating the molar mass of Fe2O3 is a straightforward process once you understand its molecular composition. Here’s a breakdown:
Step 1: Find the Atomic Weights
- Iron (Fe): Approximately 55.845 u (atomic mass units)
- Oxygen (O): Approximately 16 u
Step 2: Calculate the Molar Mass of Fe2O3
Given that Fe2O3 has two iron atoms and three oxygen atoms, we multiply the atomic weights by their respective counts:
2 x Atomic Weight of Iron (Fe) + 3 x Atomic Weight of Oxygen (O) = 2 x 55.845 u + 3 x 16 u = 111.69 u + 48 u = 159.69 u
Therefore, the molar mass of Fe2O3 is approximately 159.69 grams per mole.
