Dear student
The energy released = total energy of proton and anti-proton.
Rest energy of a proton/anti-proton = 938.257 MeV (Mega-electronvolts) (using E = mc^2)
2 * 938.257 = 1876.514 MeV (because there are 2 particles)
1876.514 * 10^6 = 1876514000 eV (get from MeV to eV)
1 eV = 1.60 * 10^-19J (convert to joules using charge of an electron (because we're in electron volts))
So 1876514000 eV = (1876514000 * (1.60 * 10^-19)) J
= 3.00 * 10^-10 J
