1. The problem statement, all variables and given/known data What is the total translational kinetic energy of the gas molecules of 0.450 mol of air at atmospheric pressure that occupies a volume of 5.00 L (0.00500 m3)? 2. Relevant equations P=2/3(N/V)<Ktr> N= 0.450 mol V= 5.00L Want to find Ktr 3. The attempt at a solution The problem is I don't know the pressure to use this formula or how to figure out what it is from the given information, if that's possible.
