Human lungs have evolved to breathe oxygen at a pressure as that in the atmosphere, 0.21 atm. If a particular heliox mixture to be carried by a scuba diver is at a pressure of 7.00 atm, what should be the partial pressure due to helium in order to maintain the pressure due to oxygen at 0.21 atm?
Answers: 2
, where 
= total partial pressure of all the component gases in the mixture, 
= partial pressure of helium gas, and 
= partial pressure of oxygen gas.
