FeO3 = 103.845 g/mol
Fe = 55.845 g/mol
(55.845 g/103.845 g) x 100% = 53.8% Fe in 2FeO3

What are wrought iron's component elements?
The metal iron has one component- iron. It is an element. Different types of iron, such as wrought iron or cast iron may contain other materials, such as carbon. You need to specify what you are referring to.
What is the permeability of iron?
A stable, nonmagnetic austenitic alloy steel having extremely low magnetic permeability especially in the unannealed condition, and consisting essentially of, in percent by weight, carbon 0.35 to 0.45, manganese 14 to 16.5, phosphorus 0.05 max., sulfur 0.07 to 0.12, silicon 0.55 to 1.15, nickel 3.5 to 5.5, nitrogen 0.12 max., chromium, 0.50 max. and the balance iron and incidental impurities.
How many kilograms of iron are in 639 kilograms of Fe2O3?
First you need to find the atomic weights of all the elements involved and add them up (including how many atoms of the same element there are) to find the total molecular mass.Fe = 55.9 grams × 2 atoms = 111.8 gramsO = 16 grams × 3 atoms = 48 grams________________________________________Fe2O3 = 159.8 gramsThen you take the weight of iron in one mole of the compound and divide it by the total weight to get its percent composition.111.8 grams Fe ÷ 159.8 Fe2O3 grams = .6996 = 69.96% Fe in Fe2O3Then we apply this percentage to 639 kg. The thought process is as follows: if there is 69.96% of iron in Fe2O3 by weight, then 69.96% of 639 kg of the substance is iron.69.96% of 639 kg = .6996 × 639 = 447.1 kilograms of Fe in 639 kilograms of Fe2O3
What is the percent elongation at fracture for the cast iron?
.2-5.4%, higher values in this range are obtained as a result of ferritizing
What is the mineral used to create iron ore?
Iron is the mineral. Iron is an element and as such, is not composed of any other materials, though iron ore comes out of the ground mixed with many other minerals. The ore must then be processed to extract the pure iron for practicle use.
What caues by chemical reation of iron and oxygen?
iron rusts 2 Fe+3O2 = 2FeO3
What is the equation for sodium thiosulphate and iron nitrate please?
Fe(NO3)2+ Na2S2O3-----> 2NaNO3+ S2+ 2FeO3
What is the chemical equation when iron oxide reacts with hydrogen chloride?
2feo3+2 Hcl _ 2 fecl + 2h2o
Is 2FeO3 plus 3 - 4Fe plus 3 CO2 Balanced?
Assuming you mean 2FeO3+3C ---> 4Fe+3CO2, yes, it is balanced.
What is the difference between atomic percent and weight percent?
Atomic percent is based on the number of atoms in a sample. So if the sample has x number of oxygen atoms and x number of iron atoms it would report 50% oxygen and 50% iron (atomic percent). Weight percent is based on the mass of the elements detected. So if we used the above example and reported the results as weight percent we would get 22.3% oxygen and 77.7% iron. Weight percent takes into consideration the mass or atomic weight of the elements and not just the number of atoms. Most people use weight percent although for chemistry atomic percent may be more useful.
Why is atomic mass an average number?
The type of element an atom belongs to is determined by the number of protons in the nucleus. Iron, for example, always has 26 protons. The number of neutrons can vary. In naturally occurring iron there are four stable isotopes iron-54 (5.82 percent) 28 neutrons iron-56 (91.66 percent) 30 neutrons iron-57 (2.19 percent) 31 neutrons iron-58 (0.33 percent) 32 neutrons When doing calculations it is assumed the iron is close to this mixture and so the atomic mass will be calculated as the average weight of an iron atom.
What is the chemical composition for grade ggg40 ductile iron?
Percent by weight: Carbon (C) 3.70, Silicon (Si) 2.50, Manganese (Mn) 0.40 The rest is iron (Fe)
Molecular weight of iron?
The atomic weight of iron is 55.8 u.
What is the percent yield for iron if the reaction of 65.0 g of iron(III) oxide produces 42.0g of iron?
The percent yield in this case is 89,25 %.
Is a dime iron?
NOO dime is 91.67 percent copper and 8.33 percent nickel. it is NOT made of iron.
Will iron lose weight while rusting?
No. In fact, iron will gain weight because of the added weight of the oxygen.
How do you canvert H iron weight?
unit weight of 203x102 mm h iron
