1 mole of any substance contains
6.02 x 10^23
atoms
It's avogadro's number :)
the answer is there number of atoms
1 mole Fe = 6.022 x 1023 atoms Fe1 mole Fe = 55.845g Fe (atomic weight in grams)Convert grams Fe to moles Fe.400g Fe x (1mol Fe/55.845g Fe) = 7.16mol FeConvert moles Fe to atoms Fe.7.16mol Fe x (6.022 x 1023atoms Fe/1mol Fe) = 4.31 x 1024 atoms Fe
To determine the number of iron atoms in a 23.0 g iron block, you would first calculate the number of moles of iron using the molar mass of iron (55.85 g/mol). Then, you would use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles of iron to atoms.
Both a mole of magnesium Mg and a mole of iron Fe contain Avogadro's number of atoms of each element, which is approximately 6.022 x 10^23. This makes them both representative samples of their respective elements in terms of the number of atoms present.
To find the number of moles, you need to divide the number of atoms by Avogadro's number, which is about 6.022 x 10^23 atoms/mol. So, 5.98 x 10^24 atoms of iron would be approximately 9.93 moles of iron.

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.
Since a mole of a metal is generally considered to be Avogadro's Number of atoms of the metal, the answer is 3.5 times Avogadro's Number or 2.1 X 1024 atoms, to the justified number of significant digits.
Avogadros number (approximately). The atomic weight of iron is 55.845. Avogadros number , the number of atoms in a mole of an element, or the number of molecules in a mole of a compound is 6.023 X 1023
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.
A mole is that number of molecular units of a substance. The number is called the Avogadro constant, or Avogadro's number. (It is defined as the no. of atoms in 12 grams of carbon-12). For example, Iron has the chemical formula Fe. So a mole of iron is (Avogadro's no.) Fe atoms. Water has the formula H2O. A mole of water, then, is (Avogadro's no.) H2O molecules.
