Step-by-step explanation:

First, let's rewrite the balanced equation here:

Fe2O3 + 3 H2 --> 2 Fe + 3 H2O

The equation tells us that 3 moles of H2 reacts with 1 mole of Fe2O3 producing 2 moles of Fe and 3 moles of H2O.

We have 12.66 g of H2.

Let's transform it to moles using the following formula:

n = m/MM

MM of H2 = 2 g/mol

n = 12.66/2

n = 6.33 moles

So:

3 moles of H2 ---- 2 moles of Fe

6.33 moles of H2 ---- x moles of Fe

3x = 12.66

x = 12.66/3

x = 4.22 moles of Fe

Now let's transform moles of Fe into grams:

m = n*MM

MM of Fe = 55.845 g/mol

m = 4.22*55.845

m = 235.67 g

Answer: 235.67 g of Iron
