The standard formation of this law includes terms for mole fraction solubility and its namesake's constant.
One term from this law can be described as the limit as q approaches zero of the surface number density over the number density at free space. A term for the salt molality is multiplied by the Sechenov constant in one modification of this law for ionic solutions. One constant from this law also appears in the formulation of its namesake's adsorption isotherm. Carbon (*) dioxide deviates from the trend of this law's namesake coefficient increasing with larger molecular weights. Replacing that constant from this law with a term for vapor pressure produces Raoult's law. The standard formation of this law includes terms for mole fraction solubility and its namesake's constant. This law may also be applied to explain decompression sickness in divers. For 10 points, name this law stating that the amount of dissolved gas in a liquid is proportional to its partial pressure. 
One term from this law can be described as the limit as q approaches zero of the surface number density over the number density at free space.
