Multiply by 8x10^10 J to get your answer.In summary, to calculate the energy release from fissioning 0.001 kg of uranium 235, one must first determine the number of U-235 atoms using Avogadro's number. Then, multiply this number by the energy released per fission and finally by 8x10^10 J to get the total energy released.

suppose that 0.001kg of uranium 235 (92 proton number) could be persuded to fission completely

show that the energy release would be 8x10^10 J

thanks

p.s if one could explain how they did it that would be great too thanks

We don't do your homework, we help you do your homework. Do you know the daughter products of the reaction?

first part is

nucleaon number/mass number = 92+0=X+54+0 =>38
atomic number/proton number = 235+1=98+X+3 =>136

i can prove the energy release using e=mc^2 and 1.66x10^-27

but its just the last part i can't do which is

suppose that 0.001kg of uranium 235 could be persuded to fission completely

show that the energy release would be 8x10^10 J

heres the question anyway

Determine the number of U-235 atoms in 0.001 kg (think Avogadro's number), then muliply the energy released per fission, and that will give the energy produced by fissioning all the atoms in 0.001 kg.
 

What is the formula for calculating energy release from fission of 0.001kg Uranium 235?

The formula for calculating energy release from fission of 0.001kg Uranium 235 is E = mc^2, where E is the energy release, m is the mass of Uranium 235, and c is the speed of light (3 x 10^8 m/s).

How do you convert mass into energy in this calculation?

In this calculation, mass is converted into energy through the famous equation E = mc^2, where c is the speed of light. This equation shows the relationship between mass and energy, stating that mass and energy are interchangeable.

How much energy is released from fission of 0.001kg Uranium 235?

Using the formula E = mc^2, we can calculate the energy release from fission of 0.001kg Uranium 235. Plugging in the values, we get E = (0.001kg)(3 x 10^8 m/s)^2 = 9 x 10^10 Joules. Therefore, approximately 90 billion Joules of energy are released from fission of 0.001kg Uranium 235.

What is the significance of calculating energy release from fission of 0.001kg Uranium 235?

Calculating the energy release from fission of 0.001kg Uranium 235 is important because it helps us understand the amount of energy that can be harnessed from a small amount of nuclear material. This information is crucial for nuclear power generation and also for understanding the potential destructive power of nuclear weapons.

Are there any safety concerns when handling 0.001kg Uranium 235?

Yes, there are significant safety concerns when handling 0.001kg Uranium 235, as it is a highly radioactive and toxic material. Proper precautions and regulations must be followed to ensure the safety of those handling it and the surrounding environment.
