Calculate the Internal Energy and Energy of Molecules of Gas

In order to calculate the energy of molecules of the Gas firstly we need the need the mass of the gas in kilogram (kg).

Furthermore, we also require the molecular mass of the gas.

The temperature of the gas in Kelvin, K

Note that the,

 Avogadro's Number = 6.02e26 molecules.

Furthermore, the value of k = 1.38e-23 J/K

Performing the calculation, gives us,

The number of Moles.

The number of Molecules.

The Total Internal Energy of the Gas computed by the formula Total Energy  = 3/2 kT

And finally, the Total Energy of the Molecules
