Question : With symbols having their usual meanings, which one among the following is used as the standard for defining atomic mass units?
Option 1: C-12
Option 2: H-1
Option 3: O-8
Option 4: N-14
Correct Answer: C-12
Solution : The correct option is C-12.
The symbol used as the standard for defining the atomic mass unit (amu) is "u". The atomic mass unit is a unit of mass used to express atomic and molecular weights. One atomic mass unit is defined as one-twelfth of the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state, with a value of approximately 1.66053906660 × 10-27 kg.
