6.355 x 10e10 atoms of iron contain 58,93.e-13 grams
Five iron atoms have a mass of 1.3155 x 10-22 grams.
Rusted iron is FeO, iron oxide. 63.8 grams FeO (1 mole FeO/71.85 grams)(6.022 X 1023/1 mole FeO) = 5.35 X 1023 atoms of iron oxide -------------------------------------------
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 ===================
738 grams iron are equivalent to:- 12,626 moles- 76.10e23 atoms
6.355 x 10e10 atoms of iron contain 58,93.e-13 grams
That depends. For the most common form of Iron (Iron-56), there are 56 grams. You may also call 6.02 X 10^23 atoms/molecules a "mole" of atoms/molecules.

The mass is 2.86 grams but the weight will be 0.028 Newtons.
Yes. One mole (6.02 x 10 to the 23 atoms) would weigh 197 grams.
If you suppose that the nail is pure iron, this material has atoms not molecules.And the number of atoms in 3 g is 0,32535.10e23.

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 ===================
The answer is 38,174.10ex.23 atoms
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 --------------------------------------
