Octane, C3H18, is the primary component of gasoline. Octane burns in the presence of oxygen according to the following combustion reaction: 2 CH18 (g) + 25 0, (g) 16 CO, (g) + 18 H,0 (g) If 7.0 moles of octane burn in the presence of excess oxygen, how many grams of carbon dioxide, CO2, are produced? Note: This is a review question that involves stoichiometry and molar mass. Please include units and an appropriate number of significant figures with your answer.
