The Atomic Mass of iron is 55.845, and the number of atoms in one gram-atomic mass is the Avogadro Number 6.02 X 1023. Therefore the answer to this question is
(61/55.845) X 6.02 X 1023 = 6.6 X 1023. (Only two significant digits are justified by the significance-limiting datum 61.)
1 mole of iron atoms has the greatest mass - 55,845 g.
The number of iron moles is x(atoms)/6,022140857.10e23.
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.
The number of atoms is 28,099.10e23.
dose 23 grams of sodium and 238 grams of uranium have equal number of atoms in them
An atom's atomic number gives its number of protons. Checking the periodic table for atomic number 26, we see that its represented by the element iron. Thus, iron does have 26 protons.
354 g Fe x 1 mole Fe/55.85 g Fe x 6.02x10^23 atoms Fe/mole Fe = 3.82x10^24 atoms of iron
3.82 × 1024 Fe atoms
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.
63.55g or 63.55 grams
The number of atoms of lead is 6,68.10e23.
1 mole of iron atoms has the greatest mass - 55,845 g.
In order to compare the number of atoms, one needs to first convert the masses into moles:3 g Fe x 1 mole/55.8 g = 0.054 moles Fe2 g S x 1 mole/32 g = 0.063 moles STherefore, 2 g of sulfur contains more atoms than does 3 g of Fe. This is because 1 mole of ANY element contains 602x10^23 atoms, so the more moles you have, the more atoms you have.
The number of atoms of lead is 6,68.10e23.
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.
The number of iron moles is x(atoms)/6,022140857.10e23.
