Unformatted text preview: the amount of gas as well. Joseph Louis Gay-Lussac (1778-1823) Discovered the Law of Combining Volumes : At a given temperature and pressure, the volumes of gasses that react with one another are in the ratios of small whole numbers For example, two volumes of hydrogen react with one volume of oxygen to form two volumes of water vapor Amadeo Avogadro interpreted Gay-Lussac's data Avogadro's hypothesis : Equal volumes of gases at the same temperature and pressure contain equal numbers of molecules 1 mole of any gas (i.e. 6.02 x 10 23 gas molecules) at 1 atmosphere pressure and 0C occupies approximately 22.4 liters volume Avogadro's Law: The volume of a gas maintained at constant temperature and pressure is directly proportional to the number of moles of the gas Doubling the number of moles of gas will cause the volume to double if T and P remain constant...
