According to the Big Bang model, all of the 12C in the universe was made in stars. One process that occurs in older stars is the triple-alpha process in which three alpha particles are turned into 12C. The m of an alpha particle (an alpha particle is a 4He nucleus) is 6.646477E-27 kg. The m of 12C is 19.926464E-27 kg. How much energy is released in the triple-alpha process? Give your answer both in pJ and in MeV.
