In a vessel with a volume V=1 m3 at a temperature t=20 °C there is air with a relative humidity fi=30%. Determine the relative humidity after m=5 g of water is added to the vessel and completely evaporated. The temperature is maintained constant. The saturated vapor pressure of water at 20 °C is equal to Pnp=2.3•103 Pa. Molar mass of water m=18 g/mol.
