A container having a volume of 1 m^3 holds 23 mol of helium gas at 122◦C.Boltzmann’sconstant is1.38 ×10^−23 J/K. Assuming the helium behaves like an idealgas, what is the average kinetic energy per molecule?Answer in units of J

Thank you for the opportunity to help you with your question!

Avg K.E = (3/2) k T where k is boltzmann constant

so by substituting we get 8.176 * 10^-21 joules
