A Geiger–Muller tube is a type of gas‑filled radiation detector. It can detect particles like X‑rays, alpha particles, and beta rays (electrons). This is useful in quantizing the activity of a radioactive source or determining if an area containing radioactive material is safe to enter. Assuming that you have 1 mol 1 mol of gas, if a Geiger counter is filled with 10362 Pa 10362 Pa of argon gas at room temperature ( T = 20.0 °C ) (T=20.0 °C) , what is the density, rho , rho, of the gas in this Geiger tube?
