Question

One gallon of pure isooctane is about 230 moles. How many moles of O2 would be required to completely combust one gallon of isooctane?

Answer 1

Step-by-step explanation:

Hello,

At first, consider the balanced reaction for the combustion of the isooctane:

`C_8H_(18)+(25)/(2) O_2-->8CO_2+9H_2O`

Now, the stoichiometric relationship between the hydrocarbon and the oxygen leads to:

`molO_2=230molC_8H_(18)(((25)/(2)mol O_2 )/(1mol C_8H_(18)) )=2875molO_2`

Best regards.
