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,

oh it is true if thats what you are asking
