Answer:
The number of moles of Fe in 1.17*10^22 atoms Fe is 0.0194 moles
Explanation:
Step 1: Data given
Number of atoms of Fe = 1.17 * 10^22 atoms
Number of Avogadro = 6.022 *10^23
Step 2: Calculate number of moles Fe
Moles Fe = atoms Fe / number of Avogadro
Moles Fe = 1.17*10^22 atoms / 6.022*10^23 / moles
Moles Fe = 0.0194 moles
The number of moles of Fe in 1.17*10^22 atoms Fe is 0.0194 moles
