2. Atmospheric Mass Venus and Earth have about the same mass and radius, but the atmospheric pressure on the surface of Venus is measured to be 90 times larger than the pressure at the surface of the Earth. (a) Assuming Venus' atmosphere is pure CO2 and Earth's atmosphere is pure N2, estimate the atmospheric scale height for each planet. For simplicity you can assume that both atmospheres are isothermal with T = 550 K for Venus and T = 250...
