By Anne Marie Helmenstine, Ph.D. Updated April 28, 2019 Amedeo Avogadro (August 9, 1776–July 9, 1856) was an Italian scientist known for his research on gas volume, pressure, and temperature. He formulated the gas law known as Avogadro's law, which states that all gases, at the same temperature and pressure, have the same number of molecules per volume. Today, Avogadro is considered an important early figure in atomic theory. https://www.thoughtco.com/amedeo-avogadro-biography-606872

Amadeo Avogadro, stated another equation and gas law determining the direct relationship between the volume of a gas and its number of moles that is: A gas volume varies PROPORTIONALLY to its number of moles as long as the pressure is kept constant.   Avogadro’s equation in combination with that of Boyle and Charles originates a very important equation that defines the “ideal “gas behavior called: The ideal gas equation, that may be applied to all gases and which derives from the behavior of an hypothetical gas (an ideal gas).   This equation allows us to directly calculate the pressure, temperature, volume of moles of a gas if one knows all the other variables involved.

An ideal gas, is that which temperature, pressure and volume conditions are described by the ideal gas law, which results from the combination of the three laws of gases and Avogadro’s equation who determined the direct relationship between the volume and the quantity of a gas (moles) at constant temperature and pressure. PV = n RT Where    P is the pressure in atm                              V is the volumen in L        n is the amount of gas in moles                T  is the temperature in Kelvin ºK R is the ideal gases  constant (0.082 atm  x L / mol x °K )   Avogadro’s findings are very important to be considered as he determined that: 1 mol of any gas will always occupy 22.4L at 1atm of pressure and 273ºK (Standard or normal conditions STP ) which are the conditions at which many of the gases properties are listed.
