Question

Explain the term " atomic mass ". ​

Answer 1

Answer:

atomic mass

Explanation:

the mass of an atom. SI unit is kilogram. The quantity of matter contained in an atom.

Answer 2

Answer:

An atomic unit of mass is defined as accurately 1/12 the mass of a carbon-12 atom. The carbon-12 atom has six neutrons and six protons in its nucleus. The atomic unit mass is symbolized as AMU or amu.

1 AMU = Average of the proton rest mass and the neutron rest mass.

1 AMU = 1.67377 x 10 -27 kilogram or 1.67377 x 10 -24 gram.


Extra explanation


atomic mass, the quantity of matter contained in an atom of an element. It is expressed as a multiple of one-twelfth the mass of the carbon-12 atom, 1.992646547 × 10−23 gram, which is assigned an atomic mass of 12 units. In this scale, 1 atomic mass unit (amu) corresponds to 1.660539040 × 10−24 gram.


* What do you mean by atomic mass Class 9?
Atomic mass refers to the mass of an atom. It depicts how many times an atom of an element is heavier than one-twelth (1/12th) the mass of one atom of carbon-12 of mass of one carbon atom. ... It is measured in unit called amu (atomic mass unit). 1/12 of the mass of one atom of carbon is termed as relative atomic mass.
