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).
The mole is that amount of substance of a system that contains exactly 6.022 141 79 x 1023 specified elementary entities, which may be atoms, molecules, ions, electrons, other particles, or specified groups of such particles.he mole is that amount of substance that contains the same number of elementary entities as there are atoms in 12 g of carbon 12. When the mole is used, the entities must be specified and may be atoms, molecules, ions, electrons, other particles, or specified groups of such particles.
