Problem: 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?

FREE Expert Solution

The rms speed and the translational kinetic energy are related by the expression:

vrms=2Ekm

Also, rms speed is:

vrms=3RTM

The mass of the gas, m is calculated by:

m = (1.0)(32/1) = 32 g  of O2
