Question

Скільки енергії виділяється при ділені 50 г Урану-235, якщо в ході поділу кожного ядра виділяється енергія, що дорівнює 3,2 ⋅ 10–11 Дж?

Answer 1

Ответ:

Объяснение:

m = 50 г = 5 * 10^-2 кг

M = 235 * 10^-3 кг/моль

E0 = 3,2 * 10^-11 Дж

Е-?

Знайдемо енергію

E = E0* N, де N - число атомів Урану.

N = (E0 * m* Nа)/М  де Nа = 6,02 * 10^23 моль-1 число Авагадро

E =  (3,2 * 10^-11 * 5* 10^-2 * 6,02 * 10^23)/235 * 10^-3 = 0,409 * 10^13 (Дж)

Answer 2

Energy Released from the Fission of 50g of Uranium-235

The energy released from the fission of 50g of Uranium-235 can be calculated using the mass-energy equivalence principle, which states that the energy released is equal to the mass difference multiplied by the speed of light squared.

The formula for calculating the energy released from the fission of Uranium-235 is:

E = mc^2

Where: - E = energy released - m = mass difference - c = speed of light

Using the given information that the energy released from the fission of each nucleus is 3.2 * 10^-11 J, we can calculate the total energy released from the fission of 50g of Uranium-235.

Calculation:

First, we need to convert the mass of Uranium-235 to kilograms: - 50g = 0.05kg

Now, we can use the mass-energy equivalence principle to calculate the energy released: - E = (0.05kg) * (3.2 * 10^-11 J) - E ≈ 1.6 * 10^-12 J

Therefore, the energy released from the fission of 50g of Uranium-235 is approximately 1.6 * 10^-12 J.
