Electrons are in a two-dimensional square potential energy well with sides of length L. The potential energy is infinite at the sides and zero inside. The single-particle energies are given by (h²/8mL²) (n²+ n) where nx and ny are integers. The number of single-particle states with energy 5(h²/8mL²) is: O 1 5 3 2
