Answer:

The total pressure of the mixture is 5, 53 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. We convert the unit of pressure in mmHg into atm:

760 mmHg----1 atm

785 mmHg----x= (785 mmHgx 1 atm)/760 mmHg=1, 03 atm

P total= P 02 + P N2

P total= 4, 5 atm + 1,03 atm=5, 53 atm
