Answer:
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
