Question

What is atomic mass?

Answer 1

Answer 2

Atomic mass is the mass of one mole ( => 6.02 x 10^23 particles)

NOTE : the sum of protons and neutrons is called atomic mass number

Answer 3

The mass of an atom of an element

Answer 4

atomic mass is the mass of one atom in an element

Answer 5

The relative atomic mass of an element is the average mass of one atom of that element, taking into account the abundance of the naturally occurring isotopes, and is measured on a scale where the mass of 1 atom of carbon-12 is 12 exactly. The number has no units.

(the molar mass is the mass of one mole of atoms of an element and is measured in grams)
