Avogadro's Law

Avogadro's Law:
Tells us that for a gas at constant temperature and pressure, the volume is directly proportional to the number of moles of gas present.

Equal volumes of gases at the same temperature and pressure have the same number of particles. This relationship hold true for gases at low temperatures.

As the number of moles of a gas to increase, the volume will have to increase in order for the pressure of the system to remain constant.

The volume of 1 mole of gas (at STP) is 22.4 L
