2 of this writeup to calculate the mean free paths of electrons through the mercury vapor. Use R = 0.18 nm as the radius of mercury atoms. Compare the mean free paths to Prepare a plot of the mean free path in mm of electrons in mercury vapor against the temperature in degrees Celsius of the tube in the region of The mean free path of the mercury vapor depends on the temperature of the gas, the pressure of the vapor, the density of the gas and the density of electrons. Mean free
