Problem

How much energy is released in the following nuclear reaction?

Mass of the 21Ne = 20.993849 amu; Mass of 4He = 4.002604 amu;

Mass of a neutron = 1.008665; Mass of 24Mg = 23.985045

(a) 9.51 x 107 kJ.mol

(b) 471 kJ.mol

(c) 9.22 x 1010 kJ/mol

(d) 7.65 x 104 kJ/mol

(e) 2.47 x 108 kJ/mol

 

Solution

We’re being asked to calculate the energy released for the following nuclear reaction:

N1021e+H24en01+M1224g


To calculate the energy released for the reaction, we’re going to use the following steps:

Step 1: Calculate the mass defect (Δm).
Step 2: Calculate the mass defect (Δm) in kg.
Step 3: Calculate the energy released (E).


Step 1: Calculate the mass defect (Δm).
