Which best defines partial pressure in a mixture of gases?pressure that is exerted by all the gases of a mixture on the containerpressure that is exerted by one gas as if it occupied a container by itselfhalf of the pressure that is exerted by the gases of a mixture on the containersum of the individual pressures that are exerted by two or more gases
Accepted Solution
A:
Answer: pressure that is exerted by one gas as if it occupied a container by itself.The partial pressure of a gas follows the law of Dalton of partical pressures: each gas in a mixture exerts a pressure independently of the other gases in the mixture and the total pressure of the mixture equals the sum of the pressures (partial pressures) of all the gases in the mixture.Ptotal = P gas _1 + P gas_2 + P gas_3 + ..... + P gas_n.
