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.

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 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.
