Calculate the equivalent energy in MeV of a unified atomic mass unit.

Explanation

To calculate the equivalent energy in MeV of a unified atomic mass unit (1 amu), we will follow these steps:

### Step 1: Understand the mass-energy equivalence
According to Einstein's mass-energy equivalence principle, the energy (E) can be calculated using the formula:
\[ E = mc^2 \]
where:
- \( m \) is the mass,
- \( c \) is the speed of light in vacuum, approximately \( 3 \times 10^8 \, \text{m/s} \).
