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.

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

the answer is a and have a great day
