3. What Is The Atomic Mass Of Fe

Iron-56 (56 Fe) is the most common isotope of iron.About 91.754% of all iron is iron-56. Of all nuclides, iron-56 has the lowest mass per nucleon.With 8.8 MeV binding energy per nucleon, iron-56 is one of the most tightly bound nuclei.

1. Iron is represented as Fe and has an atomic number of 26. Iron atomic mass is 55.845 u. Know the physical and chemical properties, density, boiling and melting point, along with the uses of Iron on BYJU'S.
2. Fe: Atomic Number: 26: Atomic Mass: 55.845 atomic mass units Number of Protons: 26: Number of Neutrons: 30: Number of Electrons: 26: Melting Point: 1535.0° C: Boiling Point: 2750.0° C: Density: 7.86 grams per cubic centimeter: Normal Phase: Solid: Family: Transition Metal: Period: 4: Cost: Unknown.
3. Examples of molar mass computations: NaCl, Ca(OH)2, K4Fe(CN)6, CuSO4.5H2O, water, nitric acid, potassium permanganate, ethanol, fructose. Molar mass calculator also displays common compound name, Hill formula, elemental composition, mass percent composition, atomic percent compositions and allows to convert from weight to number of moles.
4. Explaining and how to calculate the relative atomic mass RAM or A r of an element (a) Introduction - defining relative atomic mass - carbon-12 scale. Every atom has its own unique relative atomic mass (RAM) based on a standard comparison or relative scale e.g. It has been based on hydrogen H = 1 amu and oxygen O = 16 amu in the past (amu = relative atomic mass unit).
