Air and CH4-containing gas mixture contact with pure water in a single-stage balance mixer.The total gas pressure of the mixer is 3 atm. CH4 partial at the gas inlet of the mixer pressure is 2.0 *104 Pa. 4 kg mol of pure water and 8kg mol of gas enter the mixer. air in mixer 80% of CH4 in it will pass into pure water. Quantities and compositions of all output phases calculate. (The water in the mixer is at 303 K)
