If there is a loss of 5.63 x 10-7kg of mass in a nuclear reaction, how many joules of energy would be released? recall that c = 3x108 m/s 3.92 x 104 3.92 x 1010 5.07 x 107 5.07 x 1010 6.26 x 10-24

E(energy)  is released  is calculated  as
E=MC^2
E=  energy  in   joules\
M=mass  in  Kg
C=is  the   speed  of  light

energy  is  therefore  calculated  as
((5.63 x  10^-7) {(3  x 10^8)^2)}=5.067   x  10 ^10 j( answer  D)

Sorry i dont understand the question can you rephase it?
