How to convert 3.612 x 10^23 atoms Fe

0.599800731 moles or 33.4988708 grams

Explanation:

You are given the number of atoms. To convert to moles, divide by the number of atoms in a mole:

(3.612*10^23 atoms) / (6.022*10^23 atoms per mole) = 0.599800731 moles

Then, multiply the number of moles by the molar mass of Fe (iron).

(0.599800731 moles) * (55.85 grams per mole) = 33.4988708 grams
