Atomic Masses And Composition Of Nucleus

Step 1: Understanding the concept of AMU.
An atomic mass unit (amu) is a standard unit of mass that quantifies mass on an atomic or molecular scale. The energy equivalent of 1 amu can be calculated using Einstein's equation . The energy equivalent of 1 amu is approximately 931 MeV (million electron volts).
Step 2: Explanation of each option.
- (A) 190 MeV: Incorrect. This value is not the standard energy equivalent for 1 amu.
- (B) 139 MeV: Incorrect. This value is not correct for the energy equivalent of 1 amu.
- (C) 913 MeV: Incorrect. While close, it is not the exact value.
- (D) 931 MeV: Correct. The energy equivalent of 1 amu is approximately 931 MeV, as calculated from the equation .
Step 3: Conclusion.
The energy equivalent of 1 amu is 931 MeV.
