Question

how much energy well be released by completely annihilated 100g of uranium atom.​

Answer 1

Explanation:

It is given research fact that each nucleus will release around 200 MeV of energy.

The atomic weight of Uranium is about 235 which means that 235 grams of Uranium will contain one gram mole of atoms.

Therefore, E = 200 x (1000/235) x 6.02 x 10²³ = 5.12 x 10²⁶ MeV

E = 8.21 x 10¹³ Joules for 1 kg of U
