Question

Calculate the mass defect for oxygen-16 given this data. Round to the 5es001-1.jpg decimal place.

mass of an oxygen-16 atom: 15.994914 amu

mass of a proton: 1.00728 amu

mass of a neutron: 1.00866 amu

mass defect =
amu

Answer 1

Sum of separate nucleon masses = 8(1.00728) + 8(1.00866) = 16.12752 amu

Mass defect = 16.12752 − 15.994914 = 0.132606 amu

Rounded to five decimal places: 0.13261 amu
