## anonymous one year ago Before a nuclear reaction, there is 0.01000 kg of uranium. After the nuclear reaction, there is 0.00950 kg of uranium. How much energy was released? (h = 6.63 × 10^-34 J * s) A. 9.00 * 10^16 J B. 4.50 * 10^13 J C. 1.50 * 10^5 J D. 5.00 * 10^-4 J

ok!

here we have to apply the Einstein's formula: $E = {c^2}\Delta m = 9 \times {10^{16}} \times \left( {0.01 - 0.0095} \right) = ...Joules$

ok! so we get 4.5E13! so our solution is choice B?

5. Michele_Laino

that's right!
