Text Solution

Verified by Experts

Explanation:
1) Let us assume the circle in the diagram represents mass of one carbon-12.
2) It is divided into 12 equal parts as shown in the figure.
3) Each part represents `1//12` th of atomic mass of one carbon-12.
Atomic mass unit:
One atomic mass unit is defined as the mass exactly one twelfth the atomic mass of carbon-12 isotope.
