This concept is known as Dalton's Law for gaseous mixtures. It can be mathematically represented by: P = p1 + p2 + p3 + ... To demonstrate the theory, the professor solves 1 problem: Question: (EEM-SP) A container with a capacity of 5.8 L and maintained at 27°C contains 12.8 g of oxygen, 8 g of helium, and 14 g of nitrogen. a) the total pressure of the system; b) the partial pressure of the gas with the highest molar fraction in the mixture.
