Homework Statement
above each square ince of the Earth's surface is 14.7 pounds of air. the density of air at sea level is 1.27g/l. the Earth is 7930 miles in diameter and has a mass of 5.98x10^24kg.
use this data to determine the mass in kg of the Earth's atmosphere
determine the average density in g/mm
Homework Equations
4pieR2
The Attempt at a Solution
14.7 lb air/in2 x 1kg/2.205lb x (39.37in/1m)2=1.03x10'4/m2 air above surface
then
A=4pieR2=1.97x10'8mi2 x (1km/.6214)=5.11x10'14m2
then multiply the answers for 1.534x1017kg
is that close for the "a" part?
thanks
