Answer

58.3 moles of CO_2 Explanation 1. Identify the mole ratio From the balanced equation, 15 moles of O_2 produce 12 moles of CO_2. 2. Calculate moles of CO_2 Use the mole ratio to find moles of CO_2: \[ \text{Moles of } CO_2 = \left(\frac{12}{15}\right) \times 72.9 \] 3. Perform the calculation Calculate: \[ \text{Moles of } CO_2 = \left(\frac{12}{15}\right) \times 72.9 = 58.32 \] 4. Round the result Round 58.32 to one decimal place: 58.3

Explanation
