Question by Katelynn Felder: The fractional change of mass to energy in a fission reactor is about 0.1% or 1 part in a thousand. For each k?
The fractional change of mass to energy in a fission reactor is about 0.1% or 1 part in a thousand. For each kilogram of uranium that undergoes fission, how much energy is released? If energy costs three cents per mega joule, how much is this energy worth in dollars?
Best answer:
Answer by Corinna
1kg X 0.1= 0.1kg
0.1 kg = 100,000 mg
1 mg = 90,000,000,000 joules
100,000mg = 9,000,000,000,000,000 joules
9,000,000,000,000,000 / 1,000,000= 9,000,000,000 megajoules
If energy is 3 cents per million joules or megajoule
This would cost….
9,000,000,000 X 3 cents=
27,000,000,000 cents
If 100 cents = 1 dollar……
Then we are looking at 0,000,000
