  15.37 atm
  
  Explanation:
  
  According to Dalton’s law of partial pressure, the total pressure of a mixture of gases in the tank is a sum of the individual pressures of all the gases. Hence;
  
  PT = P1 + P2 + P3 ———–
  
  So;
  
  Ptotal = Phelium + Poxygen
  
  Poxygen = 4.63 atm
  
  Ptotal = 20.0 atm
  
  Phelium = 20.0 atm – 4.63 atm
  
  Phelium = 15.37 atm
