The pressure gauge on a tank registers the gauge pressure, which is the difference between the interior and exterior pressure. When the tank is full of oxygen (O2), it contains 13.0 kg of the gas at a gauge pressure of 38.0 atm. Determine the mass of oxygen that has been withdrawn from the tank when the pressure reading is 23.0 atm. Assume the temperature of the tank remains constant.
