What is relative atomic mass?
Relative atomic mass is a dimensionless physical quantity. it is the ratio of the average mass of atoms of an element (from a single given sample or supply) to 1/12th of the mass of an atom of carbon-12 (known as the unified atomic mass unit).
- carbon is 12 instances heavier than one hydrogen atom.
- Relative atomic mass is the atomic weight compared to one/12 the mass of one atom of carbon.
- Because it's miles a comparison of atomic weight with 1/12 the mass of an atom of carbon it's far termed relative atomic mass.
Why is relative atomic mass vital?
The relative atomic mass of an element is a weighted average of the masses of the atoms of the isotopes – due to the fact if there may be a whole lot extra of one isotope then it will impact the average mass lots greater than the less ample isotope will.
Why is it referred to as relative atomic mass?
As an example - carbon is 12 times heavier than one hydrogen atom. Relative atomic mass is the atomic weight compared to at least one/12 the mass of one atom of carbon. considering that it's miles a contrast of atomic weight with 1/12 the mass of an atom of carbon it is termed relative atomic mass.
