The relative humidity of the air filling a vessel with a volume of V0 = 0.5 m3 at a temperature t0 = 23°C is equal to f = 60%. How much water needs to be evaporated into this volume until the steam is completely saturated? The saturation vapor pressure at this temperature is pH = 21.7 mm Hg. Art. Molar mass of water vapor = 18 g/mol.
