Question

Explain this statement

One Atomic Mass unit is a mass unit equal to exactly one -twelth(1/12) the mass of one atom of carbon- 12 isotope.​

Answer 1

Explanation:

The mass of one atom is usually expressed in atomic mass units (amu), which is referred to as the atomic mass. An amu is defined as exactly 112 of the mass of a carbon-12 atom and is equal to 1.6605 × 10−24 g.

Answer:The atomic mass unit (AMU or amu) of an element is a measure of its atomic mass. Also known as the dalton (Da) or unified atomic mass unit (u), the AMU expresses both atomic masses and molecular masses.

AMU is defined as one-twelfth the mass of an atom of carbon-12 (12C). 12C is the most abundant natural carbon isotope, accounting for over 98% of carbon found in nature. It has an AMU of 12.

Carbon-12 is considered a reference for all atomic mass calculations. Thus, the mass of any isotope of any element is expressed in terms of the 12C standard of AMU.
