Molecular Mass of Iron(II) Acetate Tetrahydrate

To understand the implications of using iron(II) acetate tetrahydrate in practical applications, it is important to calculate its molecular mass. The molecular mass can be calculated by adding the atomic masses of all the atoms in the formula.

– Iron (Fe): 55.85 g/mol
– Carbon (C): 12.01 g/mol (4 carbon atoms in the acetate)
– Hydrogen (H): 1.008 g/mol (8 hydrogen atoms in the acetate and 8 in the 4 water molecules)
– Oxygen (O): 16.00 g/mol (4 oxygen atoms in the acetate and 4 in the water)

Calculation

1. Iron: 1 × 55.85 g/mol = 55.85 g/mol
2. Carbon: 4 × 12.01 g/mol = 48.04 g/mol
3. Hydrogen: 8 × 1.008 g/mol = 8.064 g/mol
4. Oxygen: 8 × 16.00 g/mol = 128.00 g/mol

Adding these together:

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

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