Problem

An atom of 28Na has a mass of 27.97878 amu. Calculate the binding energy per MOLE in kJ.

Use the values:

mass of 1H atom = 1.007825 amu

mass of a neutron = 1.008665 amu

c = 2.99792 x 108 m/s

a. 6.481x1011 kJ/mol

b. 2.288x1011 kJ/mol

c. 3.725x109 kJ/mol

d. 5.052x10kJ/mol

e. 9.532x10kJ/mol

Solution

We are asked to calculate the nuclear binding energy in kJ/mol for 28Na which has an atomic mass of 27.97878


To calculate for the nuclear binding energy:

Step 1: Determine the number of protons and neutrons

Step 2: Determine the total mass of protons and neutrons

Step 3: Calculate the mass defect (∆m)

Step 4: Determine nuclear binding energy in kJ/mol
