The answer is 3,587 moles.
5.22 x 10 to the power of 22 iron atoms is equivalent to 0,087 moles.
5.0x10^25 * (1 mol / 6.022x10^23 atoms) = 83 moles of iron.
Divide it by Avogadro constant.There are 0.0088 moles
1 mole of atoms of any element is 6.022 x 1023 atoms. 1 mole of Fe = 6.022 x 1023 atoms Fe 5.98 x 1024 atoms Fe x (1mol Fe/6.022x1023 atoms Fe) = 9.93 moles Fe

5.22 x 10 to the power of 22 iron atoms is equivalent to 0,087 moles.
738 grams iron are equivalent to:- 12,626 moles- 76.10e23 atoms
9,003 x 1023 atoms of iron correspond to 1,495 moles.
5.0x10^25 * (1 mol / 6.022x10^23 atoms) = 83 moles of iron.
0.4965 moles rounded to 4 significant figures
Divide it by Avogadro constant.There are 0.0088 moles
The answer is 0,465 moles.
The number of iron moles is x(atoms)/6,022140857.10e23.
Fe, or iron, has a molar mass of 55.845 grams per mole. This means that 0.2 moles is equal to 11.2 grams of iron.
