a. If the absolute humidity of air is 27.6 g/kg, how many grams of water vapor are there in the 4.8 kg of air? b. Air at temperature 20.0°C contains some water vapor. If the partial pressure of water vapor is 1.98 kPa, what is the relative humidity of the air in %? The saturation water vapor pressure at 20.0°C is 2.34 kPa. c. If the relative humidity of air is 80 % at 18.0°C, what is the partial pressure of water vapor in the air in the unit of kPa? The saturation water vapor pressure at 18.0°C is 2.07 kPa.
