Question

Use the density of the standard atmosphere as a function of altitude to estimate the number of molecules of nitrogen (78% by volume), oxygen(21%) and argon (1%) in the entire atmosphere of the earth.

--> Professor gave us a hint and that is: Sum the masses in spherical shell around the earth (Using excel). Alternatively, fit a curve to the density data as a function of altitude, then integrate (4*pi*r^2)rho(z) dr to obtain the total mass.

Could you please kindly walk me thru this problem using excel or matlab. I really appreciate it if you help me out. Thanks in advance.
