How do you work out the total translational kinetic energy of N2 gas?
What is the total translational kinetic energy in a test chamber filled with nitrogen (N_2 ) at 2.23×10^5 Pa and 20.7°C ?
The dimensions of the chamber are 1.00 m × 6.00 m × 6.50 m.
The atomic weight of nitrogen is 28.0 g/mol, Avogadro's number is 6.022 × 10^23 molecules/mol and the Boltzmann constant is 1.38 × 10^-23 J/K.

75 J
Explanation:
Volume of the chamber(
Pressure=
Temp=293.7 K
BY Equation of state;
n=
total molecules=3.5696*6.022
now energy for Each diatomic molecule
=
For a diatomic gas degree of freedom =5
Therefore energy= (no of molecule) *(energy of each molecule)
Energy=
=74.168 J
