According to Amedeo Avogadro's hypothesis one liter of hydrogen gas one liter of oxygen gas and one liter of helium gas that are all at the same temperature and pressure should have which of the follo?

According to Amedeo Avogadro's hypothesis, one liter of hydrogen gas, one liter of oxygen gas, and one liter of helium gas at the same temperature and pressure should contain the same number of molecules. This principle emphasizes that equal volumes of gases, irrespective of their nature, contain an equal number of molecules when measured under identical conditions. Therefore, despite differences in molecular weight and composition, the volumetric comparison holds true.
