"WebMay 30, 2024 · So when you humidify air at 12°C you get a maximum vapor pressure of approximately 1.4 kPa. However, when the air is humidified at 140 kPa the vapor pressure is still only 1.4 kPa. Therefore, you have a water/air ratio of 1.4/140= 1%. Therefore, for every mol of water, you will have 100 mol of air. " - How do temperature humidity and pressure vary
