The rms speed and the translational kinetic energy are related by the expression:
Also, rms speed is:
The mass of the gas, m is calculated by:
m = (1.0)(32/1) = 32 g of O2
The total translational kinetic energy of 1.0 mole of diatomic oxygen at 50°C is:
Note that 1.0 mol of diatomic hydrogen at 50°C has a total translational kinetic energy of 4000 J.
What is the correct total translational kinetic energy?
