Answer to Question #25299 in Physical Chemistry for Jared
Determine the total pressure of a gas mixture that contains oxygen at a pressure of 150. mmHg, nitrogen at 350.mmHg pressure, and helium at a pressure of 200.mmHg. Give your answer in mmHg and in atm.
Total pressure is the sum of all partial pressures of all components:
150 mmHg + 350 mmHg + 200 mmHg = 700 mmHg
700 mmhg = 0.92 atm
