A mixture of `C_(2)H_(2)` and `C_(3)H_(8)` occupied a certain volume at `80mm` Hg. The mixture was completely burnt to `CO_(2)` and `H_(2)O` (I). When the pressure of `CO_(2)` was found to be `230mm` Hg at the same temperature and volume, the fraction of `C_(2)H_(2)` in mixture is .

A mixture of C_(2)H_(2) and C_(3)H_(8) occupied a certain volume at 80 mm Hg. The mixture was completely burnt to CO_(2) and H_(2)O(l) . When the pressure of CO_(2) was found to be 230 mm Hg at the same temperature and volume, the mole fraction of C_(3)H_(8) in the mixture is :

A mixture of CH_(4) and C_(2)H_(2) occupied a certain volume at a total pressure equal to 63 torr. The same gas mixture was burnt to CO_(2) and H_(2)O(l).CO_(2)(g) alone was collected in the same volume and at the same temperature, the pressure was found to be 99 torr. What was the mole fraction of CH_(4) in the original gas mixture?
