how many moles of air are there in 1m^3 near sea surface at temperature 27 degre

Question

how many moles of air are there in 1m^3 near sea surface at temperature 27 degrees celcius? What if instead of air, it is pure oxygen? Sea-surface pressure=1013hPa. Assume ideal gas behavior. how many moles of air are there in 1m^3 near sea surface at temperature 27 degrees celcius? What if instead of air, it is pure oxygen? Sea-surface pressure=1013hPa.

Explanation / Answer

using the ideal gas equation:

pV = nRT

T=27+273=300 K

p=1013 hectopascals = 101300 Pa

V= 1m^3

n= (1.013x10^5x1)/(8.314*300)

n=40.61 moles

no. of moles is same for oxygen
