Dalton and Grahams law

Question

5.Nitrogen has a pressure of 593 mmHg, oxygen has a pressure of 160

        mmHg, argon has a pressure of 7 mmHg. What is the total pressure of a

        container that is filled with these gases.

Answer 1

As I said in the other problem, Dalton's law says you can add the partial pressures of the gases. Here you would get

593 + 7 + 160 = 760 mmHg
