Dalton's law - Volume-based concentration
The formula provides a way to determine the volume-based concentration of any individual gaseous component.
Dalton’s law is not strictly followed by real gases, with deviations being considerably large at high pressures. Under such conditions the volume occupied by the molecules can become significant compared to the free space between them. In particular, the short average distances between molecules raises the intensity of intermolecular forces between gas molecules enough to substantially change the pressure exerted by them. Neither of those effects are considered by the ideal gas model.Related formulas
