On a certain humid day, the mole fraction of the water vapour in air at 25∘C is 0.0287. If total pressure of air is 0.977 bar, calculate the partial pressure of water vapour in air and relative humidity if the vapour pressure of water at 25∘C is 0.0313 bar. The partial pressure of water vapour (PH2O) and relative humidity (RH) respectively are:

Answer» On a certain humid day, the mole fraction of the water vapour in air at $25^{\circ} C$ is 0.0287. If total pressure of air is 0.977 bar, calculate the partial pressure of water vapour in air and relative humidity if the vapour pressure of water at $25^{\circ} C$ is 0.0313 bar. The partial pressure of water vapour ( $P_{H_{2} O}$ ) and relative humidity ( $R_{H}$ ) respectively are:
