The radius of the earth is 6370km, the atmospheric pressure at sea level is 1 bar and the density at sea level is 1.2 kg/m^3.
estimate the mass of the atmosphere assuming the height of the atmosphere is 11km.

The mass of atmosphere equals

Step-by-step explanation:

Since the earth can be assumed to be as sphere ,to calculate the mass of the atmosphere we need to calculate the volume of the atmosphere.

The volume of atmosphere can be found by subtracting the volume of earth from the volume of the sphere formed by envelop of atmosphere around the earth as indicated in the attached figure

Mathematically we have

\

Now since it is given that 1 cubic meter of atmosphere weighs 1.2 kilogram thus the mass of the whole atmosphere equals

36

step-by-step explanation:

answer:   x*94 +688*6   = 267*100

94x+4128=26700    

94x=22572     /94

x=240.128
