Stoichiometry A vessel of volume 1000 m³ contains air which is saturated with water vapour. The total pressure and temperature are 100 kPa and 20°C respectively. Assuming that the vapour pressure of water at 20°C is 2.34 kPa, the amount of water vapour (in kg) in the vessel is approximately 34 20 25 17 34 20 25 17 ANSWER DOWNLOAD EXAMIANS APP
