The energy equivalent of a mass defect of - 0.1710 amu is which of the following

Question

Quizplus · Accepted Answer

Using the mass-energy equivalence formula E=mc^2, and converting the mass defect from amu to kg (1 amu = 1.66 x 10^-27 kg), we can calculate the energy equivalent:

E = Δm c^2
E = (-0.1710 amu) (1.66 x 10^-27 kg/amu) (2.998 x 10^8 m/s)^2
E = -2.556 x 10^-11 J

Therefore, the energy equivalent of a mass defect of -0.1710 amu is -2.556 x 10^-11 J, which is answer choice D.
