Answer to Question #222688 in General Chemistry for Ali e

Question

Combustion reactions are a notable source of carbon dioxide in the environment. Using the following balanced equation, how many grams of carbon dioxide are formed when 100.00 g of propane (C3H8) is burned? Express your answer to the correct number of significant figures. Be sure to show all steps completed to arrive at the answer.

Answer 1

C₃H₈ + O₂ = 3CO₂ + 4 H₂O

Moles of C₃H₈ = 100 / 44 = 2.28 mole .

Moles of CO₂ = ( 3 × 2.28 ) mole .

Mass of CO₂ = ( 3× 2.28 )× 44 gram .

= 300.96 gram .
