A scuba diver has a tank with an internal volume of 2500 cm^3 air tank which is pressurized to 22 MPa at 27 deg C. After diving for 20 min she notices that the air pressure has reduced to 6 MPa while the temp of the tank dropped to 18 deg C. Find what is the mass of air that the diver has breathed through her lungs during the dive?
