blue whale 5.0×10^3 L 0.0℃ 1.00 atm air mass 28.98 g/mol

blue whale 5.0×10^3 L 0.0℃ 1.00 atm air mass 28.98 g/mol

 

 

The adult blue whale has a lung capacity of 5.0×10^3 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℃ and 1.00 atm,

assuming the air behaves ideally.

PV = nRT

n = PV / RT

= [(1.00) (5.0×10^3)] / [(0.08206) (273.15+0.0)]

= 223 mol

---> 공기의 몰수

 

 

 

223 mol × (28.98 g/mol)

= 6463 g

= 6.46 kg

---> 공기의 질량
