Question
A plasma-screen TV contains thousands of tiny cells filled
with a mixture of Xe, Ne, and He gases that emits light of
specific wavelengths when a voltage is applied. A particular
plasma cell, 0.900 mm x 0.300 mm x 10.0 mm, contains
4% Xe in a 1:1 Ne:He mixture at a total pressure of 500 torr.
Calculate the number of Xe, Ne, and He atoms in the cell and
state the assumptions you need to make in your calculation.
