Understanding the Formula Mass of Iron(II) Phosphate

When it comes to chemistry, one of the essential concepts is understanding the formula mass of compounds. In this article, we will delve into the specifics of Iron(II) Phosphate, including its formula, properties, and practical applications.

What is Iron(II) Phosphate?

Iron(II) Phosphate, also known as ferrous phosphate, is an inorganic compound with the chemical formula Fe3(PO4)2. This compound consists of iron in the +2 oxidation state and phosphate groups. It is commonly found in nature and can be used in various applications, such as fertilizers, dietary supplements, and as a pigment in some paints.

The Chemical Formula

The chemical formula for Iron(II) Phosphate is Fe3(PO4)2. This indicates that the compound is made up of three iron (Fe) atoms and two phosphate (PO4) groups. The phosphate group consists of one phosphorus (P) atom bonded to four oxygen (O) atoms.

Calculating the Formula Mass

To calculate the formula mass of Iron(II) Phosphate, we need to consider the atomic masses of each element in the compound:

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

Now, we can calculate the formula mass of Fe3(PO4)2:

1. Iron: 3 atoms × 55.85 g/mol = 167.55 g/mol
2. Phosphorus: 2 atoms × 30.97 g/mol = 61.94 g/mol
3. Oxygen: 8 atoms × 16.00 g/mol = 128.00 g/mol

Now, add these values together:

\[
167.55 \, \text{g/mol (Fe)} + 61.94 \, \text{g/mol (P)} + 128.00 \, \text{g/mol (O)} = 357.49 \, \text{g/mol}
\]

Therefore, the formula mass of Iron(II) Phosphate (Fe3(PO4)2) is approximately 357.49 g/mol.
