protons plus neutrons
The atomic mass unit is used to express the measure of the atomic mass.
expressed in unified atomic mass unit, amuHowever, for practical purposes in the laboratory the relative atomic mass is used so the unit would be gram. (Relative atomic mass compares the mass of all elements to that of the carbon-12 isotope taken as exactly 12)
The weight of a football is a non-example of atomic mass. Atomic mass refers to the average mass of an atom of a chemical element, while the weight of a football is a measure of the force of gravity acting on the football due to its mass.
Saturn is not the name of a chemical element and therefore does not have any atomic mass unit.
The unit used to measure weighted average atomic mass is atomic mass unit (amu). This unit is a standard for atomic and molecular mass measurements in chemistry and is defined as one twelfth of the mass of an atom of carbon-12.
No. Atomic mass is a measure of mass, not charge.
The atomic mass unit is used to express the measure of the atomic mass.
We are not using electron mass. We measure atomic mass by Mass of neutrons and protons.
This is a question on Answers.com whereas atomic mass is a physical measure.
Atomic mass is measured by atomic mass unit(amu) . It is given by 'u' i.e. unified mass.
You Use Atomic Mass Number
Their mass is measured in atomic units 1 atomic unit is 1.660538782×10−27 kg A Proton has a mass of 1.007276466 u (u is the symbol for Atomic Mass) A Neutron has a mass of 1.008664915 u

Atomic mass is so small you can't actually measure it. So, just like carbon dating, you have to use a relative mass.
AMU=Atomic Mass Unit
Atomic mass is the measure of a mass of one atom in relation to 1/12 mass of Carbon 12 atom and measured in atomic mass unit(amu) or Dalton unit or grams/mol.Relative atomic mass is also the relative mass but does not have a unit but a ratio number.
Since the Earth is not a single atom, nor a collection of similar atoms, it does not have an atomic mass. Atomic mass is a measure of how much matter is contained by a specific atom.
