CHEM 302 Chapter Notes - Chapter 2: Sea Salt, Ideal Gas Law, Density
Document Summary
Problems: 1 scale height of the martian atmosphere. On mars the atmosphere is mainly co2, the temperature is 220 k, and the acceleration of gravity is 3. 7 m s-2. Compare to the scale height of the earth"s atmosphere: 2 scale height and atmospheric mass. Many species in the atmosphere have mass concentrations that decrease roughly exponentially with altitude: z( ) 0( ) exp z h (1) where h is a species-dependent scale height: if r (z) is horizontally uniform, show that the total atmospheric mass m of such a species is given by m. 0( )h (2) where a is the surface area of the earth: equation (2) allows a quick estimate of the total atmospheric mass of a species simply from knowing its scale height and its concentration in surface air. Let us first apply it to air itself.
