Dalton's Law

In chemistry and physics, Dalton's law (also called Dalton's law of partial pressures) states that in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases. This empirical law was observed by John Dalton in 1801 and is related to the ideal gas laws.

# One analogue of this law for another quantity is called Amagat's law, and its namesake also names the atomic mass unit, and contributed to stoichiometry when he stated that elements combine in a ratio of whole numbers. Used to calculate concentrations of component elements, name, for 10 points, this law of chemistry named for an English scientist that states that the force exerted by a gas is equal to the sum of the forces of each component gas.
