iOS app is also available. Fe3 (PO4)2 molecular weight Molar mass of Fe3 (PO4)2 = 357.477722 g/mol This compound is also known as Iron (II) Phosphate. Convert grams Fe3 (PO4)2 to moles or moles Fe3 (PO4)2 to grams In chemistry, the molar mass of a chemical compound is defined as the mass of a sample of that compound divided by the amount of substance in that sample, measured in moles. The molar mass is a bulk, not molecular, property of a substance. The molar mass is an average of many instances of the compound, which often vary in mass due to the presence of isotopes.

So, the molar masses of Fe and of Fe³⁺ are the same: 55.845 g/mol. The mass of Fe³⁺ in 1 mol of compound depends on the formula of the compound. For example, 1 mol of Fe (NO₃)₃ contains 1 mol of Fe³⁺ ions (55.845 g). But 1 mol of Fe₂ (SO₄)₃ contains 2 mol of Fe³⁺ions (111.690 g).

For instance, the atomic mass of 54Fe is 53.9396147 u (9 significant 2.34 Mass-mole-number conversions require the use of masses in grams, molar masses, and divide by the molar mass.

The molar mass is an average of many instances of the compound, which often vary in mass due to the presence of isotopes. Most commonly, the molar mass is computed from the standard atomic weights and is thus a terrestrial average and a function of the relativ Fe2O3 molecular weight Molar mass of Fe2O3 = 159.6882 g/mol This compound is also known as Ferric Oxide or Hematite or Iron (III) Oxide.

hi there. the question really says it all the mass of hemoglobin is 0.347% of four Fe atoms. hemoglobin contains 4 Fe atoms so basically 55.85 atomic mass of Fe x 4 = 223.4 a.m.u so its 0.347 % of
