• Analyzing reactions rxn
• Using Dimensional Analysis

Step-by-step explanation:

Step 1: Define

Identify

[rxn] 6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

[Given] 2 mol C₆H₁₂O₆

[Solve] mol CO₂

Step 2: Identify Conversions

[rxn] 6CO₂ → C₆H₁₂O₆

Step 3: Convert

1. [DA] Set up:
   `\displaystyle 2 \ mol \ C_6H_(12)O_6((6 \ mol \ CO_2)/(1 \ mol \ C_6H_(12)O_6))`
2. [DA] Multiply [Cancel out units]:
   `\displaystyle 12 \ mol \ CO_2`
