 A nuclear power plant provides 1012 J of electrical power each day to run a small community by using heat from the fission of uranium-235 to turn turbines. The mass deficit due to the fission of one uranium-235 atom is 3 x 10–25 grams. How much mass is converted to energy per day to power the community? (Hint: c = 3.0 x 108 m/s, h = 6.63 x 10–34 J s.)
(A) 10–23 g
(B) ...
(C) ...
(D) ...
(E) ...
