Iron Pyrophosphate Molecular Weight: Properties and Applications

Iron pyrophosphate (Fe₄(P₂O₇)₃) is an inorganic compound widely used in food fortification, pharmaceuticals, and industrial applications. Understanding its molecular weight is essential for precise formulation and dosage calculations.

Molecular Weight of Iron Pyrophosphate
The molecular weight of iron pyrophosphate is calculated by summing the atomic masses of its constituent elements:
– Iron (Fe): 55.845 g/mol × 4 = 223.38 g/mol
– Phosphorus (P): 30.974 g/mol × 6 = 185.844 g/mol
– Oxygen (O): 15.999 g/mol × 21 = 335.979 g/mol

Total Molecular Weight = 223.38 + 185.844 + 335.979 ≈ 745.20 g/mol

Key Properties
– Chemical Formula: Fe₄(P₂O₇)₃
