N2, O2, and CO2 are all contained in a sealed flask. The total pressure of the mixture is 12.5atm. Calculate the partial pressure of CO2 if the pressure of N2 is 3.7atm and O2 is 4.8atm.

Respuesta :

Answer:

The partial pressure of C02 is 4 atm

Explanation:

The sum of the partial pressures of the gases that make up a gaseous mixture is equal to the total pressure of said mixture, according to Dalton's law:

P total = P N2 + P 02 + PC02

PC02 = P total -  P N2 - P 02= 12, 5 atm -3, 7 atm -4,8 atm= 4 atm
