3.1 (10 points) Calculate the density of the atmosphere at the surface of Mars, where the pressure is 650 Pa and the temperature is typically 253 K, with a CO2 (44×10-3 kg/mol) atmosphere., and. (b) Compare each of these densities with that of the earth’s atmosphere, which is 1.20 kg/m3 . 3.2 (5 points) Venus (with an average temperature of 730 K and pressure of 92 atm, with a CO2 atmosphere 3.3 (5 points) Saturn’s moon Titan, where -178 oC the pressure is 1.5 atm and the temperature is with a N2 (28×10-3 kg/mol)atmosphere

PV = nRT => Density= D= nM/V where M is molar mass
V= nM/D, PnM/D = nRT => PM/RT =D
Density of Mars = 650*44*10^-3 / 253* 8.314 = 0.0136
Density of Venus = 92*10^5*1.013*44 *10^-3 / 730*8.314 = 67.564
Density of Titan = 1.5 *1.013*10^5*28*10^-3 / 95*8.314 = 5.387
Density of Earth's Atmosphere= 1.2 kg/m^3
