Answer:
Mass of Fe = 32.55 g
Explanation:
Molar Mass of Fe atom = 55.845 g/mol
It means,
1 mole of Fe contains = 55.845 g ..............(1)
From mole concept,
<u>1 mole </u>of Fe contain = atom ..........(2)
Replace 1 mole in equation (2) by 55.845 g , it become :
55.845 g of Fe contain = atoms
Reverse the equation now
atoms of Fe contain =55.845 g
1 atom of Fe contain = g
atom contain =
on calculation,
atom contain = 32.55 g of Fe
Mass of Fe = 32.55 g
