Exactly the mass of an atom expressed in atomic units of mass (u).
mole
The Nucleus contains Protons and Neutrons which comprise practically all the atom's mass.
Clark County does (douse???) measure 8061 square miles.
an atom
It is an inaccurate model, because there is no way to measure the exact mass, path, and charge of an atom
Scientists use a unit called atomic mass unit (amu) to measure the mass of particles within an atom. This unit is based on the mass of a proton or neutron, and it helps scientists compare the mass of different atoms accurately.
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.
The relative atomic mass was first proposed by John Dalton in 1803. According to it, the mass of an atom was expressed relative to the mass of one 1H atom. The unit was later changed to 1/16 of the mass of an oxygen atom. However, this measure was discarded when 17O and 18O were discovered. In 1961 the basic unit was changed (once again) to 1/12 of the mass of a 12C atom. The mass of any atom or molecule is measured in atomic mass units (AMU) and the units is defined as 1/12 the mass of a 12Carbon atom.
A mass spectrometer is the device most commonly used to measure the nuclear mass. It works by ionizing atoms and then separating the ions based on their mass-to-charge ratio. This allows for precise measurement of the mass of the nucleus of an atom.

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.
We use atomic mass unit (amu) to measure the mass of an atom. 1 amu is equal to 1/12 th the mass of carbon-12 atom. 1 amu = 1.660 * 10^ -27 Kg. General units like Kg, pound and ounce are too big. Note- * means multiply, ^ raised to the power
