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. 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. Convert grams Fe2O3 to moles or moles Fe2O3 to grams Examples of molar mass computations: NaCl, Ca(OH)2, K4[Fe(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 and Explanation: The elemental symbol for iron is Fe, and according to my periodic table, the molecular mass is 55.845 to three decimal places. It will calculate the total mass along with the elemental composition and mass of each element in the compound.

Fe molar mass

When a compound's formula is unknown, measuring the mass of each of its significant digits, what is the mass percentage of iron in the compound Fe2O3? The units for molar mass are, therefore, grams/mole. To find the molar The molar mass of Fe2O3 is 159.7 g/mol. Fe. 2 x 55.85 = 111.70. O. 3 x. 16.0. = + 48.0 .
