Iron(II) acetate, with the chemical formula Fe(C₂H₃O₂)₂, is an important compound in various industrial and laboratory applications. Understanding its properties, including its molar mass, is crucial for those working in chemistry and related fields. In this article, we will explore the significance of iron(II) acetate, its composition, and its molar mass.
What is Iron(II) Acetate?
Iron(II) acetate is a coordination compound formed by iron in the +2 oxidation state and acetate ions. It is commonly used as a precursor in the synthesis of other iron compounds, as well as a catalyst in organic reactions. The compound appears as a light green to yellowish solid and is highly soluble in water, making it easy to work with in various solutions.
Chemical Composition
The chemical formula for iron(II) acetate can be broken down as follows:
– Iron (Fe): 1 atom
– Acetate (C₂H₃O₂): 2 molecules
This leads to the molecular formula being expressed as Fe(C₂H₃O₂)₂, which indicates that there are two acetate ions for every iron ion in the compound.
Molar Mass of Iron(II) Acetate
To calculate the molar mass of iron(II) acetate, we need to sum the molar masses of all the constituent atoms:
1. Iron (Fe): 55.85 g/mol
2. Carbon (C): 12.01 g/mol (2 atoms in acetate × 2 acetates = 4)
3. Hydrogen (H): 1.008 g/mol (3 atoms in acetate × 2 acetates = 6)
4. Oxygen (O): 16.00 g/mol (2 atoms in acetate × 2 acetates = 4)
Now, we can calculate the total molar mass:
– Iron: 55.85 g/mol
– Carbon: 4 × 12.01 g/mol = 48.04 g/mol
– Hydrogen: 6 × 1.008 g/mol = 6.048 g/mol
– Oxygen: 4 × 16.00 g/mol = 64.00 g/mol
Total Molar Mass Calculation:
\[
Molar\ Mass\ of\ Fe(C₂H₃O₂)₂ = 55.85 + 48.04 + 6.048 + 64.00 = 173.938\ g/mol
\]
Thus, the molar mass of iron(II) acetate is approximately 173.94 g/mol.
