A simple way to do solve such problems is, first find the atomic mass of iron ie ferrous. Fe. If m is the Atomic Mass then change into gram. Then that amount is known as molar mass. Always a molar mass would have 6.023 x 10^23 atoms. Hence one gram would have 6.023 x 10^23 / m.
In case of carbon 12 is the atomic mass. Hence in one gram of carbon there will be 6.023 x 10^23 / 12 ie 5.019 x 10^22 atoms .
A second person:
1 mol of Fe = 56 grams
1 gram = 1 mol of Fe/56
=(6 x 10^23)/56

How many moles of fluorine atoms are in a sample of fluorine that contains 7.45 x 1024 fluorine atoms?
Whatever be the substance the one gram mole of that substance would have 6.023 x 1023 atoms or molecules or ions in it. Hence to get the mole just divide the number given by 6.023 x 1023
How many moles in 28 grams of CO2?
The formula for methane shows that each molecule of it contains 5 atom: 1 carbon atom and 4 hydrogen atoms. The gram molecular mass of methane is 16.04. Therefore, 28 grams of methane contains 28/16.04 moles of methane and 5 times this number, or 8.7, "moles of atoms", to the justified number of significant digits.
Why does a water molecule contain two atoms but a hydrogen cholride contain only 6ne?
H20 contains three atoms - two hydrogen atoms and one oxygen atom. HCl contains two atoms - one hydrogen atoms and one chlorine atom. This is all due to valency (how many electrons an atom wishes to gain, lose, or share to form a more stable energy state), which varies from atom to atom.
How many milligram equals a gram?
1000 milligram equals a gram
How many atoms make 1 pound?
1 mole of anything always contains 6.022*1022 things; therefore, 1 mole contains 6.022*1022 atoms.
Each molecule of iron oxide fe2o3 contains how many atoms of iron?
There are two atoms of iron and three atoms of oxygen in the compound Fe2O3. The mass percent of iron is 69.943%
Does iron only contain one type of atom?
It is true. A compound contains two or more different type of atoms.
How many molecules of iron are there in iron oxide?
One molecule of iron oxide (Fe2O3) contains two iron atoms per molecule. So, for every molecule of iron oxide, there are two iron atoms, which means one iron oxide molecule contains two iron atoms.
How many iron atoms are in one molecule of iron oxide?
One molecule of iron oxide (Fe₂O₃) contains two iron atoms.
Febr2 contains how many iron atoms?
One formula unit of FeBr2 contains one iron atom.
How many atoms in iron sulfate?
Iron sulfate contains one iron atom, one sulfur atom, and four oxygen atoms. Therefore, there are a total of six atoms in iron sulfate.
How many atoms of Fe are in 0.26 mole of Fe?
A single gram atomic mass of iron is usually considered to be the functional equivalent of a mole of metallic iron, because iron atoms do not form well characterized polyatomic entities with themselves. Therefore, 0.26 "mole" of iron contains 0.26 X Avogadro's Number of atoms, or 1.6 X 1023 atoms, to the justified number of significant digits.
Iron bromide FeBr2 contains how many iron atoms?
In iron bromide FeBr2, there is 1 iron atom present.
How many atoms does Fes2 have?
Fes2, also known as iron disulfide or pyrite, contains three atoms - one iron (Fe) atom and two sulfur (S) atoms.
