Step-by-step explanation:

Step 1: Define

[RxN - Balanced] 2C + O₂ → 2CO₂

[Given] 0.25 moles O₂

[Solve] moles CO₂

Step 2: Identify Conversions

[RxN] 1 mol O₂ → 2 mol CO₂

Step 3: Stoichiometry

1. [DA] Set up:
   `\displaystyle 0.25 \ moles \ O_2((2 \ mol \ CO_2)/(1 \ mol \ O_2))`
2. [DA] Multiply/Divide [Cancel out units]:
   `\displaystyle 0.5 \ mol \ CO_2`
