Question

a gas mixture is comprised of 32% oxygen and the rest is nitrogen. If the scuba tank is pressurized to a total pressure of 132 atm what are the partial pressures of the oxygen and nitrogen inside the tank?

I'm having trouble understanding how to find partial pressures. Can someone explain the concept to me so that I can be able to at least set up the problem on my own

Answer 1

the partial pressure is the total pressure, multiplied by the fraction of the gas involved

in this case
...ppO = .32 * 132 atm
...ppN = (1 - .32) * 132 atm
