Answer to Question #164184 in Chemistry for Ava Brooke

Question

Using the following chemical equation how many grams of carbon dioxide can be produced by burning 18.49 g of butane?

C₄H₁₀ + 5O₂ -> 3CO₂ + 4H₂O

Answer 1

According to the equation, equal numbers of moles of butane and carbon dioxide must be used and produced, respectively. From here:

m(CO₂) = m(C₄H₁₀) × Mr(CO₂) / Mr(C₄H₁₀) = 18.49 g × 44.01 g / 58.12 g = 12.76 g

Answer: 12.76 g
