Step-by-step explanation:

Step 1: Define

[RxN - Balanced] 6HCl + Fe₂O₃ → 2FeCl₃ + 3H₂O

[Given] 10.4 mol HCl

Step 2: Identify Conversions

[RxN] 6 mol HCl = 3 mol H₂O

Step 3: Stoichiometry

1. Set up:
   `\displaystyle 10.4 \ mol \ HCl((3 \ mol \ H_2O)/(6 \ mol \ HCl))`
2. Multiply/Divide:
   `\displaystyle 5.2 \ mol \ H_2O`
