Question

explain average atomic mass number​

Answer 1

• The average mass (sometimes referred to as atomic weight) of part|a component|part|a part} is that the weighted average mass of the atoms in an exceedingly present sample of the element.
• Average lots area unit typically expressed in unified mass units (u), wherever one u is capable precisely one-twelfth the mass of a neutral atom of carbon-12.
• The average mass of part is that the total of the lots of its isotopes, every increased by its natural abundance (the decimal related to the % of atoms of that component that area unit of a given isotope).

Answer 2

The weighted average mass of the atoms in a naturally occurring sample of an element is the average atomic mass (also known as atomic weight). Average masses are commonly represented in unified atomic mass units (u), with 1 u equaling one-twelfth the mass of a neutral carbon-12 atom.

Average lots are usually measured in unified mass units (u), with one u equaling exactly one-twelfth the mass of a neutral carbon-12 atom.

The average mass of a component is the sum of all of its isotopes, multiplied by its natural abundance (the decimal related to the percent of atoms of that component that area unit of a given isotope).
