# Macroscopic Description of an Ideal Gas

A rigid tank contains 0.40 mol of oxygen (02). Determine the mass (in kg) of oxygen that must be withdrawn from the tank to lower the pressure of the gas from 40 atm to 25 atm. Assume that the volume of the tank and the temperature of the oxygen are constant during this operation.
