Understanding Iron(II) Acetate Tetrahydrate: Molar Mass and Applications

Iron(II) acetate tetrahydrate, also known as ferrous acetate, is a vital compound in various chemical processes and applications. This article will delve into its molar mass, significance, and uses in different fields.

What is Iron(II) Acetate Tetrahydrate?

Iron(II) acetate tetrahydrate has the chemical formula C4H8FeO4·4H2O. It consists of iron in its +2 oxidation state, two acetate ions, and four water molecules, emphasizing its hydrated nature. This compound is often represented in its common form as a dark green crystalline solid, known for its solubility in water.

Molar Mass of Iron(II) Acetate Tetrahydrate

To understand the properties and applications of iron(II) acetate tetrahydrate, calculating its molar mass is essential. The molar mass is the sum of the atomic weights of all the elements present in the compound.

1. Iron (Fe): 55.85 g/mol
2. Carbon (C): 12.01 g/mol – There are 4 carbon atoms in the acetate groups.
3. Hydrogen (H): 1.008 g/mol – There are 8 hydrogen atoms (4 from acetate and 4 from water).
4. Oxygen (O): 16.00 g/mol – There are 4 oxygen atoms in the acetate and 4 in the water.

Calculating the total molar mass:

– Iron: \( 55.85 \, \text{g/mol} \)
– Carbon: \( 4 \times 12.01 = 48.04 \, \text{g/mol} \)
– Hydrogen: \( 8 \times 1.008 = 8.064 \, \text{g/mol} \)
– Oxygen: \( 8 \times 16.00 = 128.00 \, \text{g/mol} \)

Now, summing these values:

\[
\text{Molar Mass} = 55.85 + 48.04 + 8.064 + 128.00 = 239.954 \, \text{g/mol}
\]

Thus, the approximate molar mass of iron(II) acetate tetrahydrate is 239.95 g/mol.
