In this article, we will delve into the molar mass of iron(II) phosphate, a compound often denoted as Fe3(PO4)2. We will explore its composition, significance, and applications, helping you grasp the importance of this compound in both academic and practical contexts.
What is Iron(II) Phosphate?
Iron(II) phosphate is an inorganic compound that consists of iron, phosphorus, and oxygen. It is commonly found in nature as the mineral vivianite. The chemical formula for iron(II) phosphate is Fe3(PO4)2, indicating that it contains three iron (Fe) atoms, two phosphate groups (PO4), and a total of eight oxygen atoms. This compound is often used in various applications, including fertilizers, ceramics, and as a pigment in paints.
Calculating the Molar Mass of Iron(II) Phosphate
To calculate the molar mass of iron(II) phosphate (Fe3(PO4)2), we first need to determine the molar masses of the individual elements involved:
– Iron (Fe): The molar mass of iron is approximately 55.85 g/mol.
– Phosphorus (P): The molar mass of phosphorus is about 30.97 g/mol.
– Oxygen (O): The molar mass of oxygen is approximately 16.00 g/mol.
Now, we can calculate the molar mass of Fe3(PO4)2 step-by-step:
1. Iron: 3 atoms × 55.85 g/mol = 167.55 g/mol
2. Phosphate (PO4): Each phosphate group contains one phosphorus and four oxygen atoms.
– Phosphorus: 1 atom × 30.97 g/mol = 30.97 g/mol
– Oxygen: 4 atoms × 16.00 g/mol = 64.00 g/mol
– Total for one phosphate group = 30.97 g/mol + 64.00 g/mol = 94.97 g/mol
– Since there are two phosphate groups in iron(II) phosphate: 2 × 94.97 g/mol = 189.94 g/mol
3. Total Molar Mass of Fe3(PO4)2:
– Total = Molar mass of iron + Molar mass of two phosphate groups
– Total = 167.55 g/mol + 189.94 g/mol = 357.49 g/mol
Thus, the molar mass of iron(II) phosphate (Fe3(PO4)2) is approximately 357.49 g/mol.
