NUCLEAR CHEMISTRY: Consider the nuclei Sn with an atomic number of 50 and mass number is 117. Determine its mass defect in kilograms if its atomic mass is 116.986 amu. The mass of a proton and neutron are 1.0073 and 1.0087 amu, respectively. Express your answers in three decimal places in scientific notation, i.e., 6.022e23 to represent 6.022× 1023. No need to include the unit. Round your answer to 3 decimal places.
