Understanding Iron(II) Acetate Tetrahydrate: Molecular Mass and Applications
Iron(II) acetate tetrahydrate, a chemical compound with the formula \( \text{C}_4\text{H}_8\text{FeO}_4 \cdot 4\text{H}_2\text{O} \), is an important compound in the field of chemistry, particularly in various industrial and laboratory applications. This article will explore its molecular mass, properties, and uses, providing a comprehensive overview for those interested in this compound.
What is Iron(II) Acetate Tetrahydrate?
Iron(II) acetate tetrahydrate is a coordination compound that consists of iron in a +2 oxidation state, coordinated with acetate ions and hydrated water molecules. The tetrahydrate indicates that there are four water molecules associated with each molecule of iron(II) acetate. This compound appears as a greenish or brownish crystalline solid and is soluble in water.
Molecular Mass of Iron(II) Acetate Tetrahydrate
To understand the molecular mass of iron(II) acetate tetrahydrate, we need to break down its components:
– Iron (Fe): The atomic mass of iron is approximately 55.85 g/mol.
– Acetate (C₂H₃O₂): Each acetate group contributes:
– Carbon (C): 2 atoms × 12.01 g/mol = 24.02 g/mol
– Hydrogen (H): 3 atoms × 1.01 g/mol = 3.03 g/mol
– Oxygen (O): 2 atoms × 16.00 g/mol = 32.00 g/mol
– Total for one acetate: 24.02 + 3.03 + 32.00 = 59.05 g/mol
– Water (H₂O): Each water molecule contributes:
– Hydrogen (H): 2 atoms × 1.01 g/mol = 2.02 g/mol
– Oxygen (O): 1 atom × 16.00 g/mol = 16.00 g/mol
– Total for one water molecule: 2.02 + 16.00 = 18.02 g/mol
Now, since there are two acetate groups in iron(II) acetate, the contribution from acetate is:
– 2 × 59.05 g/mol = 118.10 g/mol
For the four water molecules:
– 4 × 18.02 g/mol = 72.08 g/mol
Finally, we can calculate the total molecular mass of iron(II) acetate tetrahydrate:
\[
\text{Molecular mass} = \text{mass of Fe} + \text{mass of 2 acetate} + \text{mass of 4 water}
\]
\[
= 55.85 + 118.10 + 72.08 = 246.03 \, \text{g/mol}
\]
Thus, the molecular mass of iron(II) acetate tetrahydrate is approximately 246.03 g/mol.
