Understanding its molecular mass and other properties is crucial for scientists and engineers working with this compound. In this article, we will delve into the molecular mass of iron(II) acetate tetrahydrate and its significance in practical applications.
What is Iron(II) Acetate Tetrahydrate?
Iron(II) acetate tetrahydrate is a hydrated form of iron(II) acetate, which is a salt formed from acetic acid and iron(II) ions. This compound appears as a light green or bluish powder and is soluble in water. The tetrahydrate form indicates that there are four water molecules associated with each formula unit of iron(II) acetate.
Molecular Mass of Iron(II) Acetate Tetrahydrate
To calculate the molecular mass of iron(II) acetate tetrahydrate, we need to consider the contributions of all the atoms in its formula:
– 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 (from acetate) + 8 atoms (from 4 water molecules) = 14 atoms × 1.008 g/mol = 14.112 g/mol
– Oxygen (O): 8 atoms (4 from acetate and 4 from water) × 16.00 g/mol = 128.00 g/mol
Now, adding these together gives us the molecular mass of iron(II) acetate tetrahydrate:
\[
\text{Molecular Mass} = 55.85 + 48.04 + 14.112 + 128.00 = 245.002 \text{ g/mol}
\]
Thus, the molecular mass of iron(II) acetate tetrahydrate is approximately 245.00 g/mol.
