A room contains 61 m3 of air-water vapour mixture. If the room is kept at a constant 20 °C and relative humidity of 53%, how much water vapour is in the room? Give your answer in kg to three decimal places. You may take the gas constant R for water vapour to be equal to the gas constant for steam as given in the property tables.
