The atmosphere of Mars is mostly CO2 (molar mass 44.0g/mol) under a pressure of 650 Pa, which we shall assume remains constant. In many places the temperature varies from 0.0 °C in summer to - 100 °C in winter. Part A Over the course of a martian year, what are the ranges of the rms speeds of the CO2 molecules. O 1393 m/s to 1313 m/s 393 m/s to 313 m/s 39.3 m/s to 31.3 m/s 3.93 m/s to 3.13 m/s Part B Over the course of a martian year, what are the ranges of the density (in mol/m) of the atmosphere? O 286 mol/m³ to 452 mol/m3 O 2.86 mol/m³ to 4.52 mol/m3 0.286 mol/m to 0.452 mol/m3 28.6 mol/m³ to 45.2 mol/m The atmosphere of Mars is mostly CO2 (molar mass 44.0g/mol) under a pressure of 650 Pa, which we shall assume remains constant.
