A mole.
No.
Its avogadros number
I asked this question wrong. It should be Avogadros Number. Sorry!
atoms in 12 g of c-12
It is 6.02 (times) 10 to the power of 23
The unit is "per mole", or mol^-1.
There is 1 mole of atoms in 6.022 x 10^23 atoms of any element.
Its avogadros number which is 6.02 X 10^23 g/mol
Avogadro's number represents the number of units of a substance in one mole of the substance. These units may be electrons, atoms, ions, or molecules, depending on the substance.
1 mole has 6,022 140 857 (74).1023 molecules, atoms, ions.
To find the number of atoms in 55.8 grams of Fe, you need to first calculate the moles of Fe using the molar mass (55.85 g/mol). Then you can use Avogadro's number (6.022 x 10^23) to convert moles to atoms.
