Total lung capacity of a typical adult is approximately 5.0L. Approximately 20% of the air is oxygen, as air is 20% oxygen. At s

Tresset [83]

Answer:

n=0.03928 moles

Moles of oxygen do the lungs contain at the end of an inflation are 0.03928 moles

Explanation:

The amount of oxygen which lung can have is 20% of 5 L which is the capacity of lungs

Volume of oxygen in lungs =V=5*20%= 1 L= $1*10^{-3} m^3$

Temperature=T= $37^oC=273+37=310K$

Pressure at sea level = P= 1 atm= $1.0125*10^5 Pa$

R is universal Gas Constant =8.314 J/mol.K

Formula:

$n=\frac{PV}{RT}\\n=\frac{(1.0125*10^5) *(1*10^{-3})}{(8.314)*310} \\n=0.03928 mol$

Moles of oxygen do the lungs contain at the end of an inflation are 0.03928 moles
