a.Calculate the number of molecules in a deep breath of air whose volume is 2.25 L at body temperature, 37 ?C, and a pressure of 740 torr.
b.The adult blue whale has a lung capacity of 5.0Ã103 L. Calculate the mass of air (assume an average molar mass 28.98 g/mol) contained in an adult blue whaleâs lungs at 0.4 ?C and 1.07 atm, assuming the air behaves ideally.
