The mass of neutral carbon atom in ground state is

Aexact 12 u
Bless than 12 u
Cmore than 12 u
DDepends on the form of carbon such as graphite or charcoal
Correct Answer

Solution

A unit used for measurement of mass is unified atomic mass unit, which is denoted by u.

It is defined such that

$$1 u = \frac{1}{12} $$ (Mass of neutral carbon atom in its ground state)

Mass of neutral carbon atom in its ground state $$= 12 \times 1 u = 12$$ u

Thus the mass of neutral carbon atom in ground state is exact 12 u.
