Louis Yang · Answer 1

1 mole

Explanation:

m (Fe) = 112 g

n (Fe₂O₃) = ?

First you must calculate how many moles of Fe is in 112 g of Fe:

n (Fe) = m (Fe) / Ar (Fe) = 112 g / 55,85 g moles⁻¹ = 2 moles

Now, from reaction you compare moles of Fe and Fe₂O₃:

2 n (Fe₂O₃) = n (Fe)

n (Fe₂O₃) = n (Fe) / 2 = 1 mole
