Question:

Acetylene (C2H2) is burned with the stoichiometric amount of air during a combustion process. Assuming complete combustion, determine.
(a) The air-fuel ratio on a mass basis.
(b) The air-fuel ratio on a mole basis.
(c) What-if Scenario: What would the air to fuel ratio be if propene (C3H6) were burned instead of acetylene?
