The Atomic Mass is the average weight of one mole of a substance (6.022 * 10^23 atoms or molecules) in grams. For elements, this is usually around double the number of protons but varies due to isotopes containing more or fewer neutrons.
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
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)
Atomic mass is so small you can't actually measure it. So, just like carbon dating, you have to use a relative mass.
protons plus neutrons
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.
