if the binding energy per nucleon of deuteron is 1.115 Me V , find its masss defect in atomic mass unit .

Explanation

To find the mass defect of the deuteron given its binding energy per nucleon, we can follow these steps:

### Step 1: Understand the Given Information
The binding energy per nucleon of the deuteron (which is an isotope of hydrogen) is given as:
- Binding energy per nucleon = 1.115 MeV
- The mass number (A) of deuteron = 2 (since it consists of one proton and one neutron).

### Step 2: Calculate the Total Binding Energy
