**Question 12 of 18**

**Determine the mass in grams of CO₂ that are produced by the complete reaction of 11.65 grams of C₉H₂₀ (nonane) according to the following combustion reaction:**  
C₉H₂₀(l) + 14 O₂(g) → 9 CO₂(g) + 10 H₂O(g)

---

**Explanation:**

This problem involves a stoichiometric calculation for the combustion of nonane (C₉H₂₀). In this exercise, the goal is to determine how many grams of carbon dioxide (CO₂) are formed when 11.65 grams of nonane undergo complete combustion.

**Key Components:**

1. **Starting Amount:**  
   You begin with 11.65 grams of C₉H₂₀.

2. **Combustion Reaction:**  
   The balanced chemical equation for the combustion reaction shows 1 mole of nonane reacts with 14 moles of oxygen to produce 9 moles of carbon dioxide and 10 moles of water.

3. **Calculation Grid:**  
   - Various values are provided for use in stoichiometric calculations, including molecular weights and mole coefficients:
     - Molecular weight of CO₂: 44.01 g/mol
     - Molecular weight of C₉H₂₀: 128.2 g/mol
     - Mole ratio for CO₂: 9
     - Mole ratio for O₂: 14
     - Mole ratio for H₂O: 10
     - Avogadro's number: \(6.022 \times 10^{23}\)

**Process:**

To find the grams of CO₂ produced:
- Convert grams of C₉H₂₀ to moles using its molecular weight.
- Use the mole ratio from the balanced equation to find moles of CO₂ produced.
- Convert moles of CO₂ to grams using its molecular weight.

**Additional Note:**

The grid also includes terms and values like:
- “Add Factor”: To include additional calculations if needed.
- “Answer” and “Reset”: Sections to input and check answers, or reset the calculations.

This explanation helps guide a student or learner through the process of solving a stoichiometry problem involving the combustion of hydrocarbons.
