The complete combustion of octane, C8H18, a component of gasoline, proceeds as is shown below. 2 C8H18(l) + 25 O2(g) 16 CO2(g) + 18 H2O(l)
(a) How many moles of O2 are needed to burn 1.15 mol of C8H18?
(b) How many grams of O2 are needed to burn 1.40 g of C8H18?
(c) Octane has a density of 0.692 g/mL at 20°C. How many grams of O2 are required to burn 4.35 gal. of C8H18? 1 gal = 3.79 L.
