What is Iron(II) Acetate Tetrahydrate?
Iron(II) acetate tetrahydrate is a coordination compound consisting of iron in the +2 oxidation state, acetate ions, and water molecules. The tetrahydrate designation indicates that there are four water molecules associated with each formula unit of iron(II) acetate. This compound is typically found as a greenish solid and is soluble in water, making it useful in various chemical processes.
Molar Mass of Iron(II) Acetate Tetrahydrate
To understand the molar mass of iron(II) acetate tetrahydrate, we must consider the contributions of each element in the compound:
– Iron (Fe): 55.85 g/mol
– Acetate (C2H3O2): The molar mass of acetate can be calculated as follows:
– Carbon (C): 12.01 g/mol × 2 = 24.02 g/mol
– Hydrogen (H): 1.008 g/mol × 3 = 3.024 g/mol
– Oxygen (O): 16.00 g/mol × 2 = 32.00 g/mol
– Total for acetate: 24.02 + 3.024 + 32.00 = 59.044 g/mol
– Water (H2O): The molar mass of one water molecule is:
– Hydrogen (H): 1.008 g/mol × 2 = 2.016 g/mol
– Oxygen (O): 16.00 g/mol × 1 = 16.00 g/mol
– Total for one water molecule: 2.016 + 16.00 = 18.016 g/mol
– For four water molecules: 4 × 18.016 g/mol = 72.064 g/mol
Now, we can sum these values to find the total molar mass of iron(II) acetate tetrahydrate:
– Molar mass of Iron(II) acetate tetrahydrate:
– Fe: 55.85 g/mol
– 2 × acetate: 2 × 59.044 g/mol = 118.088 g/mol
– 4 × H2O: 72.064 g/mol
Adding these together:
\[
55.85 \, \text{g/mol} + 118.088 \, \text{g/mol} + 72.064 \, \text{g/mol} = 245.002 \, \text{g/mol}
\]
Thus, the molar mass of iron(II) acetate tetrahydrate is approximately 245.00 g/mol.
