4) Moles of ideal gases = 24 litres

A mole of any “ideal” gas takes up 24 litres, about the same volume as a balloon.

(1 litre volume = 10 x 10 x 10 cm3)


A mole of gas takes up 24 litres which is about the size of a standard balloon
All take up 24 litres volume (at RTP, room temperature and pressure).


Even though O2 and H2 look like this…


Oxygen and hydrogen are different in molecular size, but they both take up the same volume

… and oxygen has more shells than hydrogen, both gases still take up the same volume.


Chemistry is weird!
Isn’t chemistry weird!
