Steps to Calculate the Molar Mass of K3Fe(C2O4)3·3H2O

Calculating the molar mass of a hydrated coordination compound involves summing the atomic masses of all constituent atoms. Here’s a step-by-step breakdown:

1. Identify the components of the formula:

   • K3: Three potassium (K) atoms.
   • Fe: One iron (Fe) atom.
   • (C2O4)3: Three oxalate (C2O4²⁻) ions.
   • 3H2O: Three water molecules attached as water of crystallization.

2. Use atomic masses from the periodic table:

   • Potassium (K): 39.10 g/mol
   • Iron (Fe): 55.85 g/mol
   • Carbon (C): 12.01 g/mol
   • Oxygen (O): 16.00 g/mol
   • Hydrogen (H): 1.008 g/mol

3. Calculate the contribution of each component:

   • Potassium (K3):
     $ 3 \times 39.10 = 117.30 , \text{g/mol} $
   • Iron (Fe):
     $ 1 \times 55.85 = 55.85 , \text{g/mol} $
   • Oxalate (C2O4)3:
     Each oxalate ion contains 2 carbon atoms and 4 oxygen atoms. For three ions:
     $ 3 \times (2 \times

$3 \times (2 \times 12.01 + 4 \times 16.00) = 3 \times (24.02 + 64.Here's the thing — 00) = 3 \times 88. 02 = 264.

• Water of crystallization (3H2O):
  Each water molecule contains 2 hydrogen atoms and 1 oxygen atom. For three molecules:
  $3 \times (2 \times 1.008 + 16.00) = 3 \times (2.016 + 16.00) = 3 \times 18.016 = 54.05 , \text{g/mol}$

4. Sum all contributions:
   $117.30 + 55.85 + 264.06 + 54.05 = 491.26 , \text{g/mol}$

Because of this, the molar mass of K3Fe(C2O4)3·3H2O is 491.26 g/mol.
