Question

express the atomic mass of elements by comparing them with the atomic mass of carbon​

Answer 1

Answer:

For example, the relative isotopic mass of a carbon-12 atom is exactly 12. For comparison, the atomic mass of a carbon-12 atom is exactly 12 daltons. Alternately, the atomic mass of a carbon-12 atom may be expressed in any other mass units: for example, the atomic mass of a carbon-12 atom is about 1.998467052×10−26 kg.

Answer 2

for example the atomic mass of a carbon - 12 atoms is about 1.998467052×10 - 26 kg.
