The complete combustion of octane, C8H18, a component of gasoline, proceeds as follows:
2 C8H18(l) + 25 O2(g) 
16 CO2(g) + 18 H2O(g)
(a) How many moles of O2 are needed to burn 1.50 mol of C8H18?
(b) How many grams of O2 are needed to burn 10.0 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 15.0 gal of C8H18 (the capacity of an average fuel tank)?
(d) How many grams of CO2 are produced when 15.0 gal of C8H18 are combusted?
