What is the mass of 4 moles of fe atoms

1 answer

The molar mass of Fe (iron) is 55.845 g/mol.

To find the mass of 4 moles of Fe atoms, you would multiply the molar mass by the number of moles:

Mass = 4 moles x 55.845 g/mol
Mass = 223.38 g

Therefore, the mass of 4 moles of Fe atoms is 223.38 grams.
