Answer:
4.8 mol
Step-by-step explanation:
The balanced equation is
Fe₂O₃ + Ca₃(PO₄)₂ ⟶2FePO₄ + 3CaO
You want to convert moles of Fe₂O₃ to moles of CaO.
The molar ratio is 3 mol CaO:1 mol Fe₂O₃.
Moles of CaO = 1.6 mol Fe₂O₃ × (3 mol CaO/1 mol Fe₂O₃)
Moles of CaO = 4.8 mol CaO
The reaction will produce 4.8 mol of CaO.
