How many atoms are in 0.256 mol Fe?

For this one, you can use the formula:

# of atoms = # of moles * Avogadro's number

# of atoms = (0.256 mol) * (6.02 * 10^23)

# of atoms = 1.54 * 10^23 atoms

Hope It helped you!

take .256 times Avogadro's number which 6.02 times 10 to the 23 power this equals 1.54 times 10 to the23 power atoms of Fe
