Understanding Iron(II) Phosphate: Percent Composition and Its Importance
Iron(II) phosphate, commonly referred to as iron phosphate, is a chemical compound with the formula Fe3(PO4)2. It is an essential compound in various applications, including agriculture, food preservation, and even in the production of certain types of batteries. In this article, we will delve into the percent composition of iron(II) phosphate, its significance, and its various uses.
What is Percent Composition?
Percent composition refers to the percentage by mass of each element in a compound. It is calculated by taking the mass of each individual element in the compound, dividing it by the total mass of the compound, and then multiplying by 100. Understanding the percent composition of a compound like iron(II) phosphate is crucial for various scientific and industrial applications.
Percent Composition of Iron(II) Phosphate
To calculate the percent composition of iron(II) phosphate, we first need to determine its molar mass. The molar mass can be calculated by summing the atomic masses of all the atoms in the formula:
– Iron (Fe): The atomic mass is approximately 55.85 g/mol. In iron(II) phosphate, there are three iron atoms.
– Phosphorus (P): The atomic mass is approximately 30.97 g/mol. There are two phosphorus atoms in the formula.
– Oxygen (O): The atomic mass is approximately 16.00 g/mol. There are eight oxygen atoms in the formula.
Molar Mass Calculation
– Iron: 3 × 55.85 g/mol = 167.55 g/mol
– Phosphorus: 2 × 30.97 g/mol = 61.94 g/mol
– Oxygen: 8 × 16.00 g/mol = 128.00 g/mol
Adding these together gives us the total molar mass of iron(II) phosphate:
\[
\text{Total Molar Mass} = 167.55 + 61.94 + 128.00 = 357.49 \text{ g/mol}
\]
Percent Composition Calculation
Now that we have the total molar mass, we can calculate the percent composition of each element:
– Percent Iron:
\[
\left(\frac{167.55}{357.49}\right) \times 100 \approx 46.9\%
\]
– Percent Phosphorus:
\[
\left(\frac{61.94}{357.49}\right) \times 100 \approx 17.3\%
\]
– Percent Oxygen:
\[
\left(\frac{128.00}{357.49}\right) \times 100 \approx 35.8\%
\]
Summary of Percent Composition
– Iron (Fe): 46.9%
– Phosphorus (P): 17.3%
– Oxygen (O): 35.8%
