Calculate the average kinetic energy of the N2 molecules in a sample of N2 gas at 273K and 546K.

I have been able to come up with the equation (KE)avg=3/2RT. I just want to know if R is equal to 0.08206 as it would be in other equations.

  • Chemistry -

    I believe R is 8.314. The 0.08206 has units of L*atm and you want joules.
