The alkane 2,2,4 trimethylpentane can be used as a fuel in an ordinary engine designed for gasoline. In fact it has an "octane rating" of 100. In the fuel industry it is called iso-octane. Write a balanced equation for the combustion of this alkane with oxygen gas. Assume that the products are carbon dioxide and water. Answer the following question: If ONE mole of iso-octane is burned, how many mols of water are formed?
a. 12
b. 10
c. 9
d. 7
e. 5
