A vapour mixture having equal volumes of NH3 and N2 is to be contacted at 20oC and 1 atm with water to absorb a portion of the NH3. If 14 m3 of this mixture is brought into contact with 10 m3 of water and if equilibrium is attained, calculate the percent of the ammonia originally in the gas that will be absorbed. Both temperature and total pressure will be maintained constant during the absorption. The partial pressure of NH3 over water at 20oC is as follows
