Calculate the mass defect and binding energy per nucleon for an alpha particle (containing two protons and two neutrons) whose actual mass is 4.0028 amu (mass of proton = 1.00759 amu, mass of nuetron = 1.00898 amu).

Explanation

To calculate the mass defect and binding energy per nucleon for an alpha particle, we will follow these steps:

### Step 1: Determine the expected mass of the alpha particle
An alpha particle consists of 2 protons and 2 neutrons. We can calculate the expected mass using the formula:

\[ \text{Expected mass} = (2 \times \text{mass of proton}) + (2 \times \text{mass of neutron}) \]
