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?

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 :

16 g of O_(2) gas and x g of H_(2) occupy the same volume at the same temperature and pressure. Then x =

A mixture of O_(2) and H_(2) gases contains 20% of H_(2) gas. At a certain temperature, the total pressure of the mixture is found to be 1 bar. What is the partial pressure of O_(2) (in bar) in the mixture?

A mixture of a mol of C_(3) H_(8) and b mol of C_(2) H_(4) was kept is a container of V L exerts a pressure of 4.93 atm at temperature T . Mixture was burnt in presence of O_(2) to convert C_(3) H_(8) and C_(2) H_(4) into CO_(2) in the container at the same temperature. The pressure of gases after the reaction and attaining the thermal equilirium with atomsphere at temperature T was found to be 11.08 atm. The mole fraction of C_(2)H_(4) in the mixture is
