At an altitude of 55.00 km, the average atmospheric temperature is essentially 0 degrees C. What is the average number of air molecules per cubic centimeter of air at this altitude?© BrainMass Inc. brainmass.com October 9, 2019, 3:20 pm ad1c9bdddf
Start with this equation P=Poe ^ (-Mgx/kT)
P is the pressure at height x
Po is the pressure at sea level
x is the altitude in cm
M is the average molecular mass
g = 980 cm/sec^2 = the ...
This solution uses the equation P=Poe ^ (-Mgx/kT) to find pressure. It then uses this pressure to determine the number of moles of "air molecules" in one cubic cm.
