Energy
When 1.0 kg of coal is burned, about 3.0e7 J of energy is released. If the energy released per 23592U fission is 2.0e2 MeV, how many kilograms of coal must be burned to produce the same energy as 1.0 kg of 235nucleons 92protons U?

<br>Additional information used.
<br>
<br>Mass of proton : 1,6726 x 10^(-27) kg
<br>Mass of neutron: 1,6749 x 10^(-27) kg
<br>Mass of electron: 0,00091x10^(-27) kg
<br>
<br>
<br>Total number of protons in the 235U92 is -> 92
<br>
<br>So, that makes the number of neutrons = 143
<br>
<br>So, the total mass of nucleus is,
<br>
<br>[92 x 1,6726 x 10^(-27) kg] ...
