Kilograms represented by the mass defect for thorium-234 = 3.09 × 10-27 kgWhat is the nuclear binding energy for thorium-234?

Use Einstein’s equation, E = mc², where the mass defect is 3.09 × 10⁻²⁷ kg and the speed of light is about 3.00 × 10⁸ m/s. Then E = (3.09 × 10⁻²⁷)(3.00 × 10⁸)² = 2.78 × 10⁻¹⁰ J. So the nuclear binding energy is 2.78 × 10⁻¹⁰ J.
