(a) Calculate the number of molecules in a deep breath of air whose volume is 2.25 L at body temperature, 37oC, and a pressure of 735 torr.
(b) The adult blue whale has a lung capacity of 5.0 x 103 L. Calculate the mass of air (assume an average molar mass 28.98 g>mol) contained in an adult blue whale's lungs at 0.0°C and 1.00 atm, assuming the air behaves ideally.
