When hydrogen gas and oxygen gas combine to form water vapor, the ratio of the volumes of these gases is always 2:1:2 (assuming that temperature and pressure remain constant), since (according to Avogadro's Law) the number of molecules in a given volume of gases is the same for all elements and thus the molecules must combine in the same simple proportions.

This is an example, FTP, of what basic gas law, named for the scientist who discovered it in 1808?
