A sealed container holds 3 moles of nitrogen (N2) gas at a pressure of 3 atmospheres and a temperature of 315 K. The atomic mass of nitrogen is 14 g/mol. The Boltzmann constant is 1.38 × 10-23 J/K and the ideal gas constant is R = 8.314 J/mol•K = 0.0821 L ∙ atm/mol ∙ K. The average translational kinetic energy of a nitrogen molecule, in 10-20 J, is closest to
