Question

Atmosphere of Mars On the surface of Mars, the average temperature is -50 °C and the atmospheric pressure is only 600. Pa (pascals), which is less than 1% of that of Earth. The Martian atmosphere consists of 96% carbon dioxide, 2.1% argon, and 1.9% dinitrogen gas by volume. (Report numerical answers below in non-scientific notation, to the correct number of significant figures. Caution: Some students still have problems with significant figures at this stage.) (1) The mole fraction of dinitrogen gas is (2) The partial pressure of dinitrogen gas is Pa. (3) The figure below shows distributions of particle speeds for the argon and dinitrogen gases in the Martian atmosphere. Which curve corresponds to dinitrogen? Relative number of molecules 1 Molecular speed (4) Which gas has the highest average kinetic energy at -50 °C?
