Question
How much part of mass of carbon C-12 atom is in one unit of atomic mass?
Hint:
1 Da is defined as 1/12 of the mass of a free carbon-12 atom.
The correct answer is:
- Atomic mass of Carbon is 12 g.
- 1 Da is defined as 1/12 of the mass of a free carbon-12 atom.
- Hence, 1/12 part of mass of carbon C-12 atom is in one unit of atomic mass.
