Question

What is the correct stoichiometric ratio for an air-fuel mixture?

(a) 14.7:1

(b) 14:1

(c) 15:1

(d) 9:1

Answer 1

Right choice is (a) 14.7:1

The best explanation: The stoichiometric ratio of air-fuel is 14.7:1. It means that 14.6 parts of air and 1 part of gasoline or petrol (by mass) is the one which would give chemically correct combustion of petrol under ideal conditions.
