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

When it comes to chemistry, understanding the properties of compounds is essential for various applications, from industrial processes to laboratory experiments. One such compound is iron(III) phosphate, commonly represented by the chemical formula FePO₄. This article will delve into the molar mass of iron(III) phosphate, its calculation, and its significance in different fields.

What is Iron(III) Phosphate?

Iron(III) phosphate is an inorganic compound that consists of iron in its +3 oxidation state, phosphate ions, and plays a crucial role in various applications, including agriculture, materials science, and environmental remediation. Its chemical structure is characterized by one iron atom, one phosphorus atom, and four oxygen atoms.

Calculating the Molar Mass of Iron(III) Phosphate

To understand the molar mass of iron(III) phosphate, let’s break down its components:

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. Since there are four oxygen atoms in iron(III) phosphate, we will multiply this by four.

Now, let’s calculate the molar mass step by step:

– Molar mass of Iron (Fe): 55.85 g/mol
– Molar mass of Phosphorus (P): 30.97 g/mol
– Molar mass of Oxygen (O): 16.00 g/mol × 4 = 64.00 g/mol

Now, adding these together:

\[
\text{Molar Mass of FePO₄} = \text{Molar Mass of Fe} + \text{Molar Mass of P} + \text{Molar Mass of O}
\]

\[
\text{Molar Mass of FePO₄} = 55.85 \, \text{g/mol} + 30.97 \, \text{g/mol} + 64.00 \, \text{g/mol} = 150.82 \, \text{g/mol}
\]

Thus, the molar mass of iron(III) phosphate (FePO₄) is approximately 150.82 g/mol.
