+1995 Before a nuclear reaction, there is 0.0100 kg of uranium. After the nuclear reaction, there is 0.0090 kg of uranium. How much energy was released? (h = 6.63 × 10^-34 J • s)
+1995 there was no formula but I actually ended up finding the answer and the guest below was as well correct.thank you for your help!
Isn't this just E = Mc^2
0.01 - 0.009 =0.001 kg - loss in Mass
E = 0.001 x 299,792,458^2 = 89,875,517,873,681.764 =8.99 x 10^13 Joules
Note: I don't think you need Planck's constant in this calculation. It is generally used to calculate the energy of a photon of radiation when its frequency is known.
