Understanding the Molecular Mass of Ferric Phosphate
Ferric phosphate, also known as iron(III) phosphate, is an important compound in various fields, including agriculture, chemistry, and materials science. One of the critical aspects of ferric phosphate that researchers and industry professionals often need to understand is its molecular mass. In this article, we will delve into the molecular mass of ferric phosphate, its significance, and how it is calculated.
What is Ferric Phosphate?
Ferric phosphate is a chemical compound with the formula FePO₄. It is composed of iron (Fe), phosphorus (P), and oxygen (O) atoms. Ferric phosphate can exist in several forms, including anhydrous, monohydrate, and other hydrated forms, each with varying molecular masses. Its applications range from serving as a dietary supplement to its use in fertilizers and as a pigment in various products.
Calculating the Molecular Mass of Ferric Phosphate
To calculate the molecular mass of ferric phosphate, we need to consider the atomic masses of each constituent element:
– Iron (Fe): Approximately 55.85 g/mol
– Phosphorus (P): Approximately 30.97 g/mol
– Oxygen (O): Approximately 16.00 g/mol
The molecular formula of ferric phosphate, FePO₄, indicates that it contains one iron atom, one phosphorus atom, and four oxygen atoms. Therefore, the molecular mass is calculated as follows:
\[
\text{Molecular Mass of FePO₄} = (1 \times 55.85) + (1 \times 30.97) + (4 \times 16.00)
\]
Calculating each component:
– Iron: \(1 \times 55.85 = 55.85\) g/mol
– Phosphorus: \(1 \times 30.97 = 30.97\) g/mol
– Oxygen: \(4 \times 16.00 = 64.00\) g/mol
Now, summing these values:
\[
\text{Total Molecular Mass} = 55.85 + 30.97 + 64.00 = 150.82 \text{ g/mol}
\]
Thus, the molecular mass of ferric phosphate (FePO₄) is approximately 150.82 g/mol.
