Fr-223 undergoes alpha decay and produced -8.9x108 kJ/mol of energy in the process. Determine the actual mass (in g/mol) of the produced At-219 nucleus. Mass of Fr-223 = 223.020 g/mol; Mass of He-4 = 4.003 g/mol Mass of proton = 1.0078 amu; Mass of neutron = 1.0087 amu Speed of light = 3.00 x 108 m/s 1 amu = 1 g/mol = 1.66 x 10-27 kg 1 MeV = 1.60 x 10-13 J
