###### Question details

The average atmospheric pressure at sea level is 1013.25 mb, or
14.7 pounds per square inch. Using this information, calculate the
total mass of the atmosphere. Convert your final answer to
kilograms. Assume that the earth is a sphere and that the elevation
of the surface is exactly sea level everywhere. Hint: The formula
for the surface area of a sphere is S = 4πr^{2}, where r =
the radius of the earth = 6370 km. Show all work in the space
provided below.
