Question
The mass of a neutral carbon atom in ground state is:
✓
Answer
- Exact 12u
In nuclear physics, a unit used for measurement of mass is unified atomic mass unit, which is denoted by u.
It is defined such that
$1\text{u}=\frac{1}{12}\times$ (Mass of neutral carbon atom in its ground state)
Mass of neutral carbon atom in its ground state = 12 × 1u = 12u
Thus, the mass of neutral carbon atom in its ground state is exactly 12u.
