Understanding Iron(II) Phosphate: Molar Mass, Properties, and Applications
Iron(II) phosphate, also known as ferrous phosphate, is an inorganic compound with the chemical formula Fe3(PO4)2. This compound plays a significant role in various industrial applications, including agriculture, pharmaceuticals, and materials science. One of the key aspects to understand when dealing with iron(II) phosphate is its molar mass. In this article, we will explore the molar mass of iron(II) phosphate, its properties, and its applications.
What is Molar Mass?
Molar mass is defined as the mass of one mole of a substance, typically expressed in grams per mole (g/mol). It is calculated by summing the atomic masses of all the atoms present in the compound’s molecular formula. For iron(II) phosphate, we will break down its components to calculate the molar mass accurately.
Calculating the Molar Mass of Iron(II) Phosphate
To calculate the molar mass of iron(II) phosphate (Fe3(PO4)2), we need to consider the atomic masses of iron (Fe), phosphorus (P), and oxygen (O):
– Atomic mass of Iron (Fe): approximately 55.85 g/mol
– Atomic mass of Phosphorus (P): approximately 30.97 g/mol
– Atomic mass of Oxygen (O): approximately 16.00 g/mol
Step-by-Step Calculation:
1. Iron (Fe): There are 3 iron atoms in the formula.
– 3 × 55.85 g/mol = 167.55 g/mol
2. Phosphorus (P): There are 2 phosphorus atoms in the formula.
– 2 × 30.97 g/mol = 61.94 g/mol
3. Oxygen (O): There are 8 oxygen atoms in the formula (4 from each phosphate group).
– 8 × 16.00 g/mol = 128.00 g/mol
Total Molar Mass:
Now, we can sum these values to find the total molar mass of iron(II) phosphate:
\[
\text{Molar Mass of Fe3(PO4)2} = 167.55 \, \text{g/mol} + 61.94 \, \text{g/mol} + 128.00 \, \text{g/mol} = 357.49 \, \text{g/mol}
\]
Therefore, the molar mass of iron(II) phosphate is approximately 357.49 g/mol.
