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.

∙ 12y agoThere 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

How many atoms of iron are in meat?
there are i dom
How many atoms are there in solid iron?
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.
How many atoms in 10 mg of iron?
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 ===================
How many iron atoms would there be in 169 milligrams 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 --------------------------------------
How many iron atoms are in 354g of iron?
The answer is 38,174.10ex.23 atoms
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.
How many atoms are there in iron?
Iron is composed of single atoms, so 1.
