Nitrous oxide, N2O, has been used as a dental anesthetic. Suppose that the average speed of an N2O molecule at 25°C is 377 m/s. (It is actually 379 m/s.) Calculate the kinetic energy (in joules) of an N2O molecule traveling at this speed.
I have worked or given generous hints to most of the above. If you want more help you will need to show some effort on your part for the others. If you have no idea where to start, please explain, in detail, exactly what it is you don't understand about the problem or your solution.
