If nitrogen gas has a density of 1.14 g/L, and an unknown gas has a density of 1.08 g/L at the same temperature and pressure, what is the ratio of the rate of effusion of the known gas to the rate of effusion of nitrogen

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.
