The number of particles (atoms or molecules) in a substance is known as Avogadro's constant and is 6.02 x 1023 particles per mole. The mole is the amount of a substance that contains the same number of particles as the number of atoms in 12 grams of carbon-12. If we consider uranium 238 as the largest isotopic component of natural uranium, and as it consists of atoms not molecules, then 1 kilogram contains 1000/238 moles (1000 grams the mass, 238 the relative Atomic Mass), ie 4.20 moles. so the number of atoms will be 4.20 x 6.02 x 1023, or 2.529 x 1024 atoms.
There are 55.845 grams in each mole of Iron.
Avagadro's number gives us the number of atoms (or molecules, or puppies) in 1 mole of anything (6.0225 x 10exp23).
1000g/55.845g/mole=17.907moles
17.907moles x 6.0225x10exp23 = 1.078 x 10exp25 atoms of iron
1kg Fe = 1.0782453*10^25 atoms
1kg Fe = 1000g Fe *(1mol/55.85) * (6.022*10^23 atoms/1mol) =
1.000 (g Fe) / 55.85 (g/mol Fe) = 0.0179 mol Fe
0.0179 mol Fe * 6.022*1023 atoms/mole = 1.078 * 1022 atoms Fe per gram Fe (=10 kiloGigaGiga)

There are two atoms of iron and three atoms of oxygen in the compound Fe2O3. The mass percent of iron is 69.943%
Iron II chloride is FeCl2 and there are thus 3 atoms. Iron III Chloride is FeCl3 and ith has 4 atoms.

Impossible to answer without knowing a mass or a volume. But I can tell you that there are 6.022x10^23 iron atoms (one mole) for every 55.845 grams of iron. That translates to: 1.078x10^22 iron atoms per gram or given that the density of iron is 7.87 g/cm3 at 25 degrees Celsius... 8.487x10^22 iron atoms per cm3.
10 milligrams iron (1 gram/1000 milligrams)(1 mole Fe/55.85 grams)(6.022 X 1023/1 mole Fe) = 1.1 X 1020 atoms of iron ===================
169 milligrams iron (1 gram/1000 milligrams)(1 mole Fe/55.85 grams)(6.022 X 10^23/1 mole Fe) = 1.82 X 10^21 atoms of iron --------------------------------------
The answer is 38,174.10ex.23 atoms
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 is composed of single atoms, so 1.

A 88,1 gram sample of Ag contain 4,9185.10e23 atoms.
Two atoms in 2 atoms of Fe (this dose not make sense pleas edit)
It is true. A compound contains two or more different type of atoms.
There are two atoms of iron and three atoms of oxygen in the compound Fe2O3. The mass percent of iron is 69.943%
Iron II chloride is FeCl2 and there are thus 3 atoms. Iron III Chloride is FeCl3 and ith has 4 atoms.
