Understanding Iron(II) Acetate: Molecular Weight and Its Importance

Iron(II) acetate, also known as ferrous acetate, is a chemical compound with the formula \( \text{C}_4\text{H}_6\text{FeO}_4 \). As a transition metal acetate, it plays a significant role in various chemical reactions and applications. One of the key aspects to understand about any chemical compound is its molecular weight, which is crucial for various scientific calculations and applications. In this article, we will explore the molecular weight of iron(II) acetate, its significance, and its applications in different fields.

What is Molecular Weight?

Molecular weight, often expressed in grams per mole (g/mol), is the weight of one mole of a substance. It is calculated by summing the atomic weights of all the atoms in the molecular formula. For iron(II) acetate, the molecular weight is determined by adding the weights of iron, carbon, hydrogen, and oxygen present in the compound.

Calculating the Molecular Weight of Iron(II) Acetate

To find the molecular weight of iron(II) acetate (\( \text{C}_4\text{H}_6\text{FeO}_4 \)), we will break down the components:

– Iron (Fe): 1 atom × 55.85 g/mol = 55.85 g/mol
– Carbon (C): 4 atoms × 12.01 g/mol = 48.04 g/mol
– Hydrogen (H): 6 atoms × 1.008 g/mol = 6.048 g/mol
– Oxygen (O): 4 atoms × 16.00 g/mol = 64.00 g/mol

Now, we can sum these values to find the total molecular weight:

\[
\text{Molecular Weight} = 55.85 + 48.04 + 6.048 + 64.00 = 173.938 \, \text{g/mol}
\]

Thus, the molecular weight of iron(II) acetate is approximately 174.0 g/mol.
