KTGO2 (10 points, 3 parts) A sample of nitrogen gas (N2) is at a temperature of 330 K and has a density of 0.490 kg m-3. NOTE: Use the atomic masses/molar masses in the periodic table in Appendix B of Katz to answer this kind of que Calculate the root-mean-squared speed for the nitrogen molecules. Vrms = 542 m/s (3.s.f) (3.33 points) You are correct. Your receipt no. is 160-4536 ( Previous Tries Calculate average translational kinetic energy per molecule for the nitrogen molecules. Kav = 6.83x10-21 j (3.s.f) (3.33 points) You are correct. Your receipt no. is 160-9264 (?) Previous Tries Calculate thermal energy per cubic meter for the nitrogen sample. Remember, this is a diatomic molecule. Eth (3.s.f) (3.34 points) Submit Answer Incorrect. Tries 2/5 Previous Tries
