In an eudiometer 20cm^3 of a gaseous hydrocarbon A is mixed with 150 cm^3 of oxygen. The combustion of A is initiated by an electric spark. After cooling and condensing the vapor the volume of the gaseous mixture is 110cm^3 of which 80cm^3 causes turbidity of limewater. The remaining volume of the gas makes a glowing splint to catch fire.

Question
