How many moles of air are necessary for the combustion of 5.00 molmol of isooctane, assuming that air is 21.0% O2O2 by volume?

67.5 moles of O2

Explanation:

2 C 8 H 18 + 27 O 2 → 16 C O 2 + 18 H 2 O

According to the balanced chemical equation, in normal air % moles of iso-octane will require 67.5 moles of oxygen to combust completely ...
