1. The problem statement, all variables and given/known data A gas of 8.00×10^19 atoms or molecules has 0.500 J of thermal energy. Its molar specific heat at constant pressure is 20.8 J/mol K. 2. Relevant equations T = 0.5/(N*specific heat) 3. The attempt at a solution I divided 8.00*10^19 by Avogadro's Constant to get the number of moles. Than I did .5/(N*20.8 J/mol K) and got 181 K. But that seems to be incorrect. Anyone know why?
