Mole Ball and Box
This beach ball and this box displace a volume of 22.4 L, the molar volume of an ideal gas at STP.
These teaching aids can be used in a general chemistry course when gas laws are being integrated into stoichiometry calculations. The ball can be passed around the room.
A mole of ideal gas at standard temperature and pressure occupies a volume of 22.4 L.
