(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

above each square ince of the earths 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 earths atmosphere

determine the average density in g/mm

2. Relevant equations

4pieR2

3. 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
