A complete combustion of octane, C8H18, a component of gasoline, proceeds as: 2 C8H18(I) +25 O2(g) -->16 CO2(g) +18 H2O(I). Atomic weights (g/mol): C=12, H=1, O=16 A. How many moles of oxygen are needed to burn 3.9 moles of octane? B. How many grams of carbon dioxide will be produced from 8.5 moles of octane? C. If 455 grams of oxygen reacts wwith 1.5 moles of octane, how many moles of the excess reactant remains unreacted?
