₉₂U²³⁸
протонов 92
нуклонов 238
нейтронов 238 -92 = 146
Δm=(92·1,00728а.е.м + 146·1,00866а.е.м.) - 238,12493а.е.м =
=92,66976а.е.м. + 147,26436а.е.м. - 238,12493а.е.м = 1,80919а.е.м
Переведем в кг:
Δm= 1,80919а.е.м. × 1,66·10⁻²⁷кг =3,0032554·10⁻²⁷кг
Е= Δmc²=3,003255·10⁻²⁷кг×(3·10⁸м/с)²= 27,029 ·10⁻¹¹Дж = 2,7·10⁻¹⁰Дж
