Using Dimensional AnalysisExplanation:

Step 1: Define

[RxN - Balanced]   2C₃H₇OH + 9O₂ → 6CO₂ + 8H₂O

[Given]   5.55 mol C₃H₇OH

Step 2: Identify Conversions

[RxN] 2 mol C₃H₇OH → 6 CO₂

Molar Mass of C - 12.01 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of CO₂ - 12.01 + 2(16.00) = 44.01 g/mol

Step 3: Stoichiometry

Set up conversion:                    Multiply/Divide:                                                                                              

Step 4: Check

Follow sig fig rules and round. We are given 3 sig figs.
