浓度 (nóng dù) — concentration (of a solution, gas, or substance); density (of population, probability, etc.)

Definition

A scientific noun meaning 'concentration' (of a solution) or 'density' (of population). The -度 suffix turns an adjective (浓 = dense/thick) into a measurable noun, so it pairs with numbers and 高/低.
