Answer:

The answer to your question is 1795.5 grams of CO₂

Step-by-step explanation:

Data

mass of carbon dioxide = ?

mass of Octane = 571.3 g

Process

1.- Write the balanced chemical reaction

C₈H₁₆ + 12O₂ ⇒ 8CO₂ + 8H₂O

2.- Calculate the molar mass of octane and carbon dioxide

Octane = (12 x 8) + (16 x 1) =96 + 16 = 112 g

Carbon dioxide = 8[ 12 + 2(16)] = 352 g

3.- Use proportions to find the mass of carbon dioxide

112 g of Octane ---------------- 352 g of carbon dioxide

571.3 g of Octane ------------- x

x = (571.3 x 352) / 112

x = 201097.6 / 112

x = 1795.5 grams of CO₂
