How many moles of air are there in a human lung with a volume of 2.4 L at STP? Explain your answer

1 answer:

5 0

One mole of any gas at STP is about 22.4 liters (even for mixtures). This number comes from the ideal gas equation by setting n=1 and STP conditions:
V=nR/P =1 mole x 0.08206Latm/molK x 237K/1atm = 22.4L

so jsut divide: 893L/22.4L/mole = 39.9 moles
