Question
What is the total mass of the earth's atmosphere? The radius of the Earth is 6.37E6 m, and atmospheric pressure at the surface is 1.013E5 N/m^2 (or Pa).
I tried this:
1.013E5 Pa = Mg/ pi(6.37E6)^2
1.013E5 Pa (denominator)= 9.8 M
solve for M: I'm coming with different ans from book.
The surface area of a sphere is 4 pi R^2
Thank you so much! What an oversight!!!
Earth is a sphere and not a circle!!!! I have the answer now! It matches that of the book!!!!
