The molar mass of iron(III) acetate, which has the chemical formula Fe(C2H3O2)3, is calculated by adding the atomic masses of all the atoms in its formula.
First, we break down the components:
- Iron (Fe): 1 atom × 55.85 g/mol = 55.85 g/mol
- Acetate (C2H3O2): 3 molecules × (2 carbon (C) + 3 hydrogen (H) + 2 oxygen (O))
- Carbon (C): 2 × 3 = 6 atoms × 12.01 g/mol = 72.06 g/mol
- Hydrogen (H): 3 × 3 = 9 atoms × 1.008 g/mol = 9.072 g/mol
- Oxygen (O): 2 × 3 = 6 atoms × 16.00 g/mol = 96.00 g/mol
Now we sum these amounts to find the total molar mass:
Total Molar Mass = 55.85 g/mol (Fe) + 72.06 g/mol (C) + 9.072 g/mol (H) + 96.00 g/mol (O) = 232.99 g/mol
Therefore, the molar mass of iron(III) acetate is approximately 232.99 g/mol.
