Step-by-step explanation:

Step 1: Define

[RxN - Unbalanced] CoCl₂ + F₂ → CoF₂ + Cl₂

[RxN - Balanced] CoCl₂ + F₂ → CoF₂ + Cl₂

[Given] 11.84 moles CoCl₂

[Solve] moles CoF₂

Step 2: Identify Conversions

[RxN] 1 mol CoCl₂ → 1 mol CoF₂

Step 3: Stoich

1. [DA] Set up:
   `\displaystyle 11.84 \ mol \ CoCl_2((1 \ mol \ CoF_2)/(1 \ mol \ CoCl_2))`
2. [DA] Multiply/Divide [Cancel out units]:
   `\displaystyle 11.84 \ mol \ CoF_2`
