Mass and energy are alternate forms of a single entity called mass-energy. The relationship between these two physical quantities is described by Einstein's equation, E = mc-, where E is energy, m is mass, and c is the speed of light (3.00 x 10 m/s ). In a combustion experiment, it was found that 12.096 g of hydrogen molecules combined with 96.000 g of oxygen molecules to form water and released 1.715 x 10 kJ of heat. Calculate the corresponding mass change in this process. (1 J= 1 kg m/s X 10 (Enter your answer in scientific notation.)
