The gases in a mixture have the following partial pressures at the same volume and temperature: 1,013,000 Pa nitrogen, 700. mmHg argon, 1.20 atm of helium, 790. torr oxygen, and 0.50 atm of carbon dioxide. What is the total pressure of the mixture in atm?
Convert each of the pressures to atm, then add them.
760 torr = 1 atm
1.01325 x 10^5 Pa = 1 atm.
