A closed vessel of 0.1 m capacity contained air at 1 bar pressure and 27°C. Hydrogen was added and the total pressure in the vessel was raised to 1.2 bar at the same temperature. Find the weight of oxygen, nitrogen and hydrogen finally in the vessel and their respective partial pressures. Air contains 77% N, by weight. Take the value of universal gas constant as 8.3143 kJ/kg K and molecular weight of air as 29. |Ans. mo, = 0.0267 kg, mN, = 0.0893 kg, mH, =0.001603 kg)
