kilograms represented by the mass defect for thorium - 234=3.09x 10-27 kg what is the nuclear binding energy for thorium - 234

Mass defect and binding energy are related as

ΔE = Δmc^2

Where

ΔE = binding energy

Δm = mass defect

c = speed of light

given

mass defect = 3.09x 10-27 kg

We know that speed of light = 3 X 10^8 m / s

ΔE = 3.09x 10-27 kg (3 X 10^8 m / s) ^2 = 2.781 X 10^-10 J / Kg
