***PLEASE EXPLAIN ALL STEPS****
A gasoline mixture consists of 10 mol% C2H5OH, 25 mol% C6H6, 20 mol% C7H8, 45 mol% C8H18.
The gasoline is burnt with air (21 mol% O2, 79 mol% N2).
The reactions are as follows:
C2H5OH + O2 → CO2 + H2O
C6H6 + O2 → CO2 + H2O
C7H8 + O2 → CO2 + H2O
C8H18 + O2 → CO2 + H2O
The water-free product consists of N2 (83.89 mol%), CO2 (15.62 mol%), C6H6, C7H8, and C8H18 (so all C2H5OH and O2 were consumed). 5.46 mol of CO2 is produced per every mol of gasoline burnt. What are the mol % of C6H6, C7H8, and C8H18. in the water-free product?
