Question

the number of atoms in 1 gram of iron are
answer fast

Answer 1

hi dear.....

Firstly calculate number of moles in 1 gm Fe

[ Moles = (weight taken ÷ atomic weight)]

Then multiply the number of moles by Avogadro’s number the get number of atoms.

[Atoms = (6.022×10^23) × (number of moles)]

1g Fe x 6.023 x 10^23 atoms Fe/55.8 g Fe = 1.08 x 10^22 atoms Fe

hope i answered your question.....

Answer 2

fe-55(aprox)

no. of moles-- given mass/molar mass = 1/55 moles=0.018 moles

no, of atoms= moles X avogadros number

                    = 0.018 X 6.022 x 10²³

sorry but i cant be bothered to multiply it
