Understanding the Molecular Mass of Ferric Phosphate
Ferric phosphate, a compound with the chemical formula FePO₄, is of considerable interest in various fields, including chemistry, agriculture, and materials science. Understanding its molecular mass is crucial for researchers and professionals working with this compound. In this article, we will delve into the molecular mass of ferric phosphate, its significance, and its applications.
What is Ferric Phosphate?
Ferric phosphate is a salt formed from iron and phosphate ions. It typically appears as a reddish-brown powder and is used in various applications, including as a food additive, in fertilizers, and in some pharmaceutical formulations. The compound is known for its role in nutrient availability in soil, particularly in the context of iron supplementation for plants.
Molecular Mass of Ferric Phosphate
To calculate the molecular mass of ferric phosphate (FePO₄), we need to consider the individual atomic masses of its constituent elements: iron (Fe), phosphorus (P), and oxygen (O).
– 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. Since there are four oxygen atoms in ferric phosphate, we multiply this value by 4.
Now, let’s perform the calculation:
1. Atomic mass of iron: 55.85 g/mol
2. Atomic mass of phosphorus: 30.97 g/mol
3. Atomic mass of oxygen (4 O): 4 × 16.00 g/mol = 64.00 g/mol
Now, we add these values together to find the molecular mass of ferric phosphate:
\[
\text{Molecular mass of FePO₄} = \text{mass of Fe} + \text{mass of P} + \text{mass of 4O}
\]
\[
= 55.85 \, \text{g/mol} + 30.97 \, \text{g/mol} + 64.00 \, \text{g/mol}
\]
\[
= 150.82 \, \text{g/mol}
\]
Therefore, the molecular mass of ferric phosphate is approximately 150.82 g/mol.
