hi, all

when dealing with mass defect,

E=mc2 --> B.E= deltam x c2 (=932Mev)....

I think c is the speed of light but how come c squre is equal to 932Mev?

Just like joules, electron volt is a unit of energy (eV). i believe if you have a mass of 1kg and your c =(3*10^8)^2 , E = 9*10^16 J
Now 1 joule = 6.24150974×1018 eV, so if we convert this we get 5.6*10^25ev.

Is that what you were wondering? I don't know the mass that was provided to you, but the calculations will follow as such. Hope it helped!!
