Strategy:
 This limiting reagent problem asks for the mass of iron produced. Calculate the moles of both reactants and compare them to the  stoichiometric ratio to identify which reactant is exhausted first.

Step 1: Calculate moles of reactants
- Moles .
- Moles .

Step 2: Identify limiting reagent
For 20 moles of , we need  moles of .
Since we have 90 moles of  (excess),  is the limiting reagent.

Step 3: Calculate mass of Iron
1 mole  produces 3 moles of .
Moles of .
