Einstein's mass-energy equation is E=mc 2 , where mass is in kilograms and the speed of light is 3.00×108m/s. The unit of energy is the joule (4.184J=1cal;1000cal=1kcal,1J=1kg⋅m2/s2).   1) Calculate the energy released, in calories, when 1  g  of matter is converted to energy, then calculate the energy released, in kilocalories, when 1  g  of matter is converted to energy.
