The adult blue whale has a lung capacity of 5.0*10^3L. Calculate the mass of air (assume an average molar mass 28.98 g/mol ) contained in an adult blue whale’s lungs at 0.3 degrees Celcius and 1.10 atm., assuming the air behaves ideally.

Calculate the number of molecules in a deep breath of air whose volume is 2.30 Liters at body temperature, 36 degrees Celcius, and a pressure of 740 torr .

    Note the correct spelling of celsius.
    Use PV = nRT and solve for n = number of moles. Then n = grams/molar mass and solve for grams.

    Do the same for the second part, solve for n = number of moles. Then convert moles to # molecules remembering that there are 6.02E23 molecules in 1 mole.
