Answer: 17.2 moles of Fe in 8.60 moles of Fe2O3
Step-by-step explanation: One mole of Fe2O3 contains 2 moles of Fe atoms.
So, the number of moles of Fe in 8.60 moles of Fe2O3 can be calculated as:
Number of moles of Fe = 2 × number of moles of Fe2O3
Number of moles of Fe = 2 × 8.60 = 17.2 moles
Therefore, there are 17.2 moles of Fe in 8.60 moles of Fe2O3.
