Answer:

n=0.03928 moles

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

Step-by-step 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:

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

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