Understanding Iron(II) Phosphate: Formula and Mass
Iron(II) phosphate, a compound with the chemical formula Fe3(PO4)2, is an important inorganic compound with various applications in agriculture, manufacturing, and chemistry. This article delves into the formula, molar mass, and significance of iron(II) phosphate, providing insights for students, researchers, and industry professionals.
What is Iron(II) Phosphate?
Iron(II) phosphate is a salt formed from iron and phosphate ions. The iron in this compound is in the +2 oxidation state, which is why it is denoted as iron(II). This compound can be found in several hydrated forms, but the most common is anhydrous iron(II) phosphate.
Chemical Structure
The chemical formula of iron(II) phosphate is Fe3(PO4)2. This indicates that each formula unit contains three iron ions (Fe²⁺) and two phosphate ions (PO4³⁻). The structure can be critical in understanding its properties and reactivity.
Calculating the Molar Mass of Iron(II) Phosphate
To calculate the molar mass of iron(II) phosphate, you need to sum the atomic masses of all the constituent atoms in the formula Fe3(PO4)2.
1. Iron (Fe): The atomic mass of iron is approximately 55.85 g/mol. Since there are three iron atoms:
\[
3 \times 55.85 = 167.55 \, \text{g/mol}
\]
2. Phosphorus (P): The atomic mass of phosphorus is about 30.97 g/mol. With two phosphate groups, we have:
\[
2 \times 30.97 = 61.94 \, \text{g/mol}
\]
3. Oxygen (O): The atomic mass of oxygen is approximately 16.00 g/mol. Each phosphate group contains four oxygen atoms, and since there are two phosphate groups:
\[
8 \times 16.00 = 128.00 \, \text{g/mol}
\]
Total Molar Mass Calculation
Now, adding these together:
\[
\text{Molar Mass of Fe3(PO4)2} = 167.55 + 61.94 + 128.00 = 357.49 \, \text{g/mol}
\]
Therefore, the molar mass of iron(II) phosphate is approximately 357.49 g/mol.
