BRAINLIEST IF RIGHT WITH EXPLANATION Oxygen is pumped into a tank at a pressure of 4.63 atm. After helium is pumped into the tank, the total pressure reaches 20.0 atm. What is the partial pressure of helium in the tank?

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
