If 7.84 x 10^7 j of energy is released from a fusion reaction, what amount of mass in kilograms would be lost? recall that c = 3 x 10^8 m/s.
7.06 x 10^24
8.71 x 10^-4
8.71 x 10^-7
8.71 x 10^-10

Answer : The mass lost would be,

Solution : Given,

Energy released =

Speed of light 'c' =

Formula used :

where,

E = energy

m = mass

c = speed of light

Now put all the given values in the above formula, we get

Therefore, the mass lost would be,

catya that's not even a b or c

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
