In a mixture of oxygen and nitrogen gas, #80.0%# of the total gas pressure is exerted by the nitrogen. If the total pressure is #"2.0 atm"#, what pressure does the oxygen exert? Chemistry Gases Gas Pressure 1 Answer Junaid Mirza Mar 20, 2018 #"0.4 atm"# Explanation: #80%#of pressure is exerted by nitrogen gas. So, #20%#of pressure will be exerted by oxygen gas. #"p"_("O"_2) = 20% "of 2 atm" = 20/100 × "2 atm" = "0.4 atm"# Answer link Related questions How can gas pressure be changed?
