# Dalton's Law

Chemistry Level 2

In chemistry and physics, Dalton's law (also called Dalton's law of partial pressures) states that the total pressure exerted by the mixture of non-reactive gases is equal to the sum of the partial pressures of individual gases. This empirical law was observed by John Dalton in $$1801$$ and is related to the ideal gas laws. If $$1$$ L of oxygen with a pressure of $$3$$ atm and $$2$$ L of nitrogen with a pressure of $$6$$ atm are mixed in a container with a volume of $$3$$ L as shown above, then what is the pressure of the gas mixture? (Assume that the temperature is constant.)
