What does dalton's law of partial pressure say? a. the pressure contributed by larger gas molecules is more than smaller gases. b. the total pressure of a gas mixture is the sum of the individual pressures. c. the total pressures of a gas mixture is the average of the individual pressures. d. the pressure of a gas can only be partially known, since no gas is truly ideal

Hi!

The Dalton's Law of partial pressure states that The total pressure of a gas mixture is the sum of the individual pressures. 

This can be written in the form of an equation in the following way:



This law was first discovered by the English Chemist John Dalton in 1802. 

This law is derived from the observation that two gases in a mixture behave independently and occupy the same volume in a closed compartment, so the contribution to pressure will depend on the sum of the individual pressures of each gas.
