Eric Muller â Exploratorium Teacher Institute 2005 A Mole of Gas 22.4 liters of gas!22.4 liters of gas is the volume of 1 mole of gas at STP(Standard Temperature and Pressure = 0 degrees C at 1ATM).Hereâs a couple of ways to see what 6.02x10 23 of gas molecules lookslike.ric Muller â Exploratorium Teacher Institute 2005 A Mole of Gas 22.4 liters of gas!22.4 liters of gas is the volume of 1 mole of gas at STP(Standard Temperature and Pressure = 0 degrees C at 1ATM).
A kilogram mole of any gas contains 6 x 1026 molecules. It occupies 22.4 m3 at 0 Â°C, or about 24 m3 at room temperature, and atmospheric pressure. When students know more about the structure of air (mainly nitrogen and oxygen) then the mass of their atoms can be estimated (they are fairly close in mass).
