Ответ: Цю формулу можна отримати, використовуючи відносні атомні маси нітрогену (14 г/моль) та оксигену (16 г/моль) та обчисливши співвідношення масових часток цих елементів у речовині. Оскільки масова частка нітрогену становить 30,43%, а масова частка оксигену - 69,57%, то співвідношення мас нітрогену та оксигену у речовині буде 30,43/14 : 69,57/16 ≈ 2/1. Отже, формула речовини - NO2.
