Understanding Iron (II) Acetate Tetrahydrate: Molar Mass and Its Significance
Iron (II) acetate tetrahydrate, a compound that combines iron, acetates, and water molecules, has garnered attention in various fields, including chemistry, agriculture, and even pharmaceuticals. In this article, we will delve into the molar mass of iron (II) acetate tetrahydrate and discuss its significance in different applications.
What is Iron (II) Acetate Tetrahydrate?
Iron (II) acetate is a coordination compound with the formula Fe(C₂H₃O₂)₂. When it is hydrated, specifically in the tetrahydrate form, it contains four water molecules associated with each formula unit. The full chemical formula for iron (II) acetate tetrahydrate can be represented as Fe(C₂H₃O₂)₂·4H₂O.
Calculating the Molar Mass of Iron (II) Acetate Tetrahydrate
To understand the properties and behavior of iron (II) acetate tetrahydrate, it is essential to calculate its molar mass. The molar mass is the mass of one mole of a substance and is expressed in grams per mole (g/mol). To calculate the molar mass of iron (II) acetate tetrahydrate, we need to sum the molar masses of all the constituent atoms.
Molar Mass Calculation Breakdown:
1. Iron (Fe):
– Atomic mass: 55.85 g/mol
– Quantity: 1
– Contribution: 55.85 g/mol
2. Acetate (C₂H₃O₂):
– Carbon (C): 12.01 g/mol × 2 = 24.02 g/mol
– Hydrogen (H): 1.01 g/mol × 3 = 3.03 g/mol
– Oxygen (O): 16.00 g/mol × 2 = 32.00 g/mol
– Total for acetate: 24.02 + 3.03 + 32.00 = 59.05 g/mol
– Since there are 2 acetate groups: 59.05 g/mol × 2 = 118.10 g/mol
3. Water (H₂O):
– Hydrogen (H): 1.01 g/mol × 2 = 2.02 g/mol
– Oxygen (O): 16.00 g/mol × 1 = 16.00 g/mol
– Total for water: 2.02 + 16.00 = 18.02 g/mol
– Since there are 4 water molecules: 18.02 g/mol × 4 = 72.08 g/mol
Total Molar Mass:
Now, we can sum all contributions:
\[
\text{Total Molar Mass} = \text{Fe} + 2 \times \text{Acetate} + 4 \times \text{Water}
\]
\[
= 55.85 \, \text{g/mol} + 118.10 \, \text{g/mol} + 72.08 \, \text{g/mol}
\]
\[
= 246.03 \, \text{g/mol}
\]
Thus, the molar mass of iron (II) acetate tetrahydrate is approximately 246.03 g/mol.
