Understanding Iron II Acetate: Molecular Weight and Its Significance

Iron II acetate, also known as ferrous acetate, is a chemical compound with several important applications in various fields, including chemistry, biology, and industry. One of the key aspects of any chemical compound is its molecular weight, which plays a crucial role in stoichiometry and the understanding of its behavior in different reactions. This article will delve into the molecular weight of iron II acetate, its significance, and its applications.

What is Iron II Acetate?

Iron II acetate is a salt formed by the reaction of iron (II) ions with acetic acid. Its chemical formula is typically represented as Fe(C₂H₃O₂)₂. This compound appears as a pale green or blue-green crystalline solid and is soluble in water. Iron II acetate is primarily used in laboratories for various experiments and has applications in the fertilizer industry due to its iron content.

Molecular Weight of Iron II Acetate

To understand the molecular weight of iron II acetate, we need to consider the molecular formula Fe(C₂H₃O₂)₂. The molecular weight is calculated by adding the atomic weights of all the atoms in the formula:

– Iron (Fe): Approximately 55.85 g/mol
– Carbon (C): Approximately 12.01 g/mol
– Hydrogen (H): Approximately 1.01 g/mol
– Oxygen (O): Approximately 16.00 g/mol

Calculating the molecular weight:

1. There is 1 iron atom:
\( 1 \times 55.85 \, \text{g/mol} = 55.85 \, \text{g/mol} \)

2. There are 4 carbon atoms (2 from each acetate):
\( 4 \times 12.01 \, \text{g/mol} = 48.04 \, \text{g/mol} \)

3. There are 6 hydrogen atoms (3 from each acetate):
\( 6 \times 1.01 \, \text{g/mol} = 6.06 \, \text{g/mol} \)

4. There are 4 oxygen atoms (2 from each acetate):
\( 4 \times 16.00 \, \text{g/mol} = 64.00 \, \text{g/mol} \)

Now, adding these values together to find the total molecular weight:
\[
55.85 \, \text{g/mol} + 48.04 \, \text{g/mol} + 6.06 \, \text{g/mol} + 64.00 \, \text{g/mol} = 173.95 \, \text{g/mol}
\]

Thus, the molecular weight of iron II acetate is approximately 173.95 g/mol.
