Understanding Iron(II) Phosphate: Molar Mass and Its Significance

When discussing chemical compounds, one of the essential properties to consider is the molar mass. In this article, we will explore the molar mass of Iron(II) Phosphate (Fe3(PO4)2), its composition, and its significance in various applications.

What is Iron(II) Phosphate?

Iron(II) Phosphate, also known as ferrous phosphate, is an inorganic compound with the formula Fe3(PO4)2. This compound consists of iron in the +2 oxidation state and phosphate ions. Iron(II) Phosphate plays a crucial role in various fields, including agriculture, medicine, and materials science.

Calculating Molar Mass of Iron(II) Phosphate

To understand the molar mass of Iron(II) Phosphate, we need to look at the individual components that make up the compound:

1. Iron (Fe): The atomic mass of iron is approximately 55.85 g/mol.
2. Phosphorus (P): The atomic mass of phosphorus is about 30.97 g/mol.
3. Oxygen (O): The atomic mass of oxygen is approximately 16.00 g/mol.

Composition Breakdown

In the formula Fe3(PO4)2, we have:

– Iron: 3 atoms × 55.85 g/mol = 167.55 g/mol
– Phosphorus: 2 atoms × 30.97 g/mol = 61.94 g/mol
– Oxygen: 8 atoms (since there are 4 oxygen atoms in each phosphate ion, and there are 2 phosphate ions) × 16.00 g/mol = 128.00 g/mol

Total Molar Mass Calculation

Now, we can sum these values to find the total molar mass of Iron(II) Phosphate:

\[
\text{Total Molar Mass} = (3 \times 55.85) + (2 \times 30.97) + (8 \times 16.00)
\]

\[
\text{Total Molar Mass} = 167.55 + 61.94 + 128.00 = 357.49 \, \text{g/mol}
\]

Therefore, the molar mass of Iron(II) Phosphate is approximately 357.49 g/mol.
