What is the binding energy of one mole of 234th90 if the mass defect is 1.908 g/mol?

The binding energy of one mole of thorium atom is

Explanation:

Binding energy is defined as the energy which holds the nucleus together. It is basically the product of mass defect and the square of the speed of light.

This energy is calculated by using Einstein's equation, which is:

Where,

E = Binding energy of the atom

= Mass defect = 1.908 g/mol =     (Conversion factor: 1 kg = 1000 g)

c = speed of light =

Putting values in above equation, we get:

Hence, the binding energy of one mole of thorium atom is

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
