Question
Atomic mass of an any element is expressed in terms of:
- Atomic mass unit
- Atomic unit
- Gram atomic weight
- All of these
Hint:
Atomic mass is also called gram atomic mass.
The correct answer is: Atomic mass unit
- The atomic mass of an element expressed in grams is called the gram atomic mass.
- For example, the atomic mass of oxygen is 16 amu, whereas the atomic mass of oxygen is 16 grams is defined as an atom.
- Atomic mass unit is defined as a unit of mass for atomic and molecular mass, it corresponds to one-twelfth of the mass of a carbon-12 atom.
