What is the total translational kinetic energy in a test chamber filled with nitrogen (N2) at 2.22×105 Pa and 20.7°C? The dimensions of the chamber are 1.00 m × 4.30 m × 6.50 m. The ATOMIC weight of nitrogen is 28.0 g/mol, Avogadro's number is 6.022 × 1023 molecules/mol and the Boltzmann constant is 1.38 × 10-23 J/K.
