Question

relative atomic mass​

Answer 1

RELATIVE ATOMIC MASS

The relative atomic mass of an element is a weighted average of the masses of the atoms of the isotopes - because if there is much more of one isotope then that will influence the average mass much more than the less abundant isotope will.

For example, chlorine has two isotopes: ³⁵Cl and ³⁷Cl.

• Relative atomic mass or atomic weight is a dimensionless physical quantity defined as the ratio of the average mass of atoms of a chemical element in a given sample to the atomic mass constant.

The atomic mass constant (symbol: mu) is defined as beinh$\frac{1}{12}$

of the mass of a carbon-12 atom.

Answer 2

Answer:

Relative atomic mass is defined as the mass mass of an atom of an element relative to the mass of 1/12 the mass of carbon-12. For example, the relative atomic mass of oxygen is 16 units when measured against standard unit of carbon 12. The relative atomic mass of sodium is 23.
