Understanding Iron(II) Phosphate: Percent Composition and Its Significance

Iron(II) phosphate, often represented by the chemical formula Fe3(PO4)2, is an important compound in various industrial applications, including fertilizers, pigments, and as a potential candidate in battery technologies. One of the key aspects of understanding this compound is its percent composition, which provides insight into its chemical makeup and potential applications. In this article, we will delve into the percent composition of iron(II) phosphate and its significance.

What is Percent Composition?

Percent composition refers to the percentage by mass of each element in a compound. It is calculated by dividing the mass of each element in a formula by the total molar mass of the compound and then multiplying by 100. This measurement is crucial for chemists and industries alike, as it helps in understanding the ratio of elements and their potential reactivity.

Calculating the Percent Composition of Iron(II) Phosphate

To calculate the percent composition of iron(II) phosphate (Fe3(PO4)2), we first need to determine its molar mass. The molar mass is calculated by summing the atomic masses of all the atoms in the formula:

1. Iron (Fe): The atomic mass of iron is approximately 55.85 g/mol. Since there are three iron atoms in the formula:
– 3 Fe = 3 × 55.85 g/mol = 167.55 g/mol

2. Phosphorus (P): The atomic mass of phosphorus is approximately 30.97 g/mol. Since there are two phosphorus atoms:
– 2 P = 2 × 30.97 g/mol = 61.94 g/mol

3. Oxygen (O): The atomic mass of oxygen is approximately 16.00 g/mol. Since there are eight oxygen atoms in the formula:
– 8 O = 8 × 16.00 g/mol = 128.00 g/mol

Now, summing these values gives us the total molar mass of iron(II) phosphate:

\[
\text{Molar Mass of Fe}_3(\text{PO}_4)_2 = 167.55 + 61.94 + 128.00 = 357.49 \text{ g/mol}
\]

Percent Composition Calculation

Now, we can calculate the percent composition of each element in iron(II) phosphate:

– Percent Iron (Fe):
\[
\text{Percent Fe} = \left( \frac{167.55 \text{ g/mol}}{357.49 \text{ g/mol}} \right) \times 100 \approx 46.87\%
\]

– Percent Phosphorus (P):
\[
\text{Percent P} = \left( \frac{61.94 \text{ g/mol}}{357.49 \text{ g/mol}} \right) \times 100 \approx 17.34\%
\]

– Percent Oxygen (O):
\[
\text{Percent O} = \left( \frac{128.00 \text{ g/mol}}{357.49 \text{ g/mol}} \right) \times 100 \approx 35.79\%
\]

Summary of Percent Composition

In summary, the percent composition of iron(II) phosphate is approximately:
– Iron (Fe): 46.87%
– Phosphorus (P): 17.34%
– Oxygen (O): 35.79%
