Для розрахунку об'єму амоніаку, який утвориться при розкладі амоній хлориду, спочатку визначимо масу амоній хлориду, яка дійсно містить амоніак (NH3).

Згідно з умовою, амоній хлорид містить 5% амоніаку. Тобто 5% з маси амоній хлориду перейде в амоніак. Тоді маса амоніаку дорівнює 5% від маси амоній хлориду:

Маса амоніаку = 0.05 * 68 г = 3.4 г.

Далі використовуємо стандартні умови для газів (0 °C і 1 атмосферний тиск), де 1 моль газу займає приблизно 22.4 літра об'єму. Молекулярна маса амоніаку (NH3) становить приблизно 17 г/моль.

Тепер можемо знайти кількість молей амоніаку:

Молі амоніаку = Маса амоніаку / Молекулярна маса

Молі амоніаку = 3.4 г / 17 г/моль ≈ 0.2 моль.

Зараз ми можемо знайти об'єм амоніаку:

Об'єм амоніаку = Кількість молей * Об'єм молекули

Об'єм амоніаку = 0.2 моль * 22.4 л/моль ≈ 4.48 л.

Отже, об'єм амоніаку, який утвориться при розкладі 68 г амоній хлориду, становить приблизно 4.48 літра при стандартних умовах.
