One such compound that often comes up in various chemical applications is Iron(II) acetate tetrahydrate. In this article, we will explore what Iron(II) acetate tetrahydrate is, its molar mass, and its significance in different fields.
What is Iron(II) Acetate Tetrahydrate?
Iron(II) acetate tetrahydrate is a coordination compound with the chemical formula \( \text{Fe(C}_2\text{H}_3\text{O}_2)_2 \cdot 4\text{H}_2\text{O} \). It consists of iron in the +2 oxidation state, two acetate ions, and four water molecules. This compound is typically found as a greenish solid and is soluble in water, making it useful in various chemical applications, including organic synthesis and analytical chemistry.
Calculating the Molar Mass of Iron(II) Acetate Tetrahydrate
The molar mass of a compound is calculated by summing the atomic masses of all the atoms in its molecular formula. For Iron(II) acetate tetrahydrate, we need to take into account the contributions from iron, acetate ions, and water molecules.
Components of Iron(II) Acetate Tetrahydrate:
1. Iron (Fe):
– Atomic mass: approximately 55.85 g/mol
2. Acetate (C₂H₃O₂):
– Each acetate ion consists of:
– Carbon (C): 2 atoms × 12.01 g/mol = 24.02 g/mol
– Hydrogen (H): 3 atoms × 1.008 g/mol = 3.024 g/mol
– Oxygen (O): 2 atoms × 16.00 g/mol = 32.00 g/mol
– Total mass for one acetate ion = 24.02 + 3.024 + 32.00 = 59.044 g/mol
– Since there are two acetate ions: 2 × 59.044 g/mol = 118.088 g/mol
3. Water (H₂O):
– Each water molecule consists of:
– Hydrogen (H): 2 atoms × 1.008 g/mol = 2.016 g/mol
– Oxygen (O): 1 atom × 16.00 g/mol = 16.00 g/mol
– Total mass for one water molecule = 2.016 + 16.00 = 18.016 g/mol
– Since there are four water molecules: 4 × 18.016 g/mol = 72.064 g/mol
Total Molar Mass Calculation
Now, we can sum all the components to find the molar mass of Iron(II) acetate tetrahydrate:
\[
\text{Molar Mass} = \text{Fe} + 2 \times \text{C}_2\text{H}_3\text{O}_2 + 4 \times \text{H}_2\text{O}
\]
\[
= 55.85 + 118.088 + 72.064
\]
\[
= 245.002 \, \text{g/mol}
\]
Therefore, the molar mass of Iron(II) acetate tetrahydrate is approximately 245.00 g/mol.
