How many iron atoms are contained in 354 g of iron?

How many iron atoms are contained in 354 g of iron? just how many metal atoms tend to be within 354 g of metal?

Firstly you need to know the molar size of metal that will be
55.845 g/mole. This worth should really be offered usually should be
memorised as metal is quite typical steel. Today 1 mole of every factor
includes 6.023x 1023 quantity of atoms which is sometimes called
Avogadro quantity.
Meaning 55.845 g of metal includes 6.023x 1023
atoms.
Therefore 354 g of metal contains (354/55.845)x 6.023x 1023
atoms.
Calculating, we have 3.8x 1024 atoms.
