In a vacuum chamber filled with argon gas at 100mTorr, a plasma is ignited resulting to 1% ionization. This is already a "hot plasma" by lab processing standards. Calculate the number density of plasma electrons (should be about the same as the argon ion density due to quasineutrality) in this 1% ionized plasma. (You can find all relevant constants in the net).

Free Electron Density in a Metal will have free electron density n = x10^ /m3. will have a number of atoms per unit volume n' = x10^ /m3. The number of atoms per unit volume multiplied by the number of free electrons per atom should agree with the free electron density above.
apparently different units, a term, torr, has been postulated; one standard atmosphere = 760 torr (1 torr = 1 mm Hg). This term was replaced in 1971 by an SI unit defined as the newton per square metre (N/m2) and called the pascal (one pascal = 7.5 × 10-3 torr).
