The complete combustion of octane, c8h18, the main component of gasoline, proceeds as follows: 2c8h18 (l) + 25 o2(g) --> 16 co2(g) + 18 h2o (g)
a. how many moles of 02 are needed to burn 1.50 mol of c8h18?
b. how many grams of 02 are needed to burn 10.0 g of c8h18?
c. octane has a density of 0.692 g/ml at 20 degrees celsius. how many grams of 02 are required to burn 15.0 gal of c8h18 (the capacity of an average file tank)?
