A mixture of C₂H₂ and C₂H₂ occupied a certain volume at 80 mm Hg. The mixture was completely burnt to CO₂ and H₂O(1). When the pressure of CO₂ was found to be 230 mm Hg at the same temperature and volume, the fraction of C₂H₂ in mixture is (a) 0.125 (b) 0.5 (c) 0.85 (d) 0.25 A mixture of C₂H₂ and C₂H₂ occupied a certain volume at 80 mm Hg.
