Mass is an intrinsic property of matter, it is not 'formed' by scientists.
Mass is solidified energy as Einstein describes E=MC2
The Higgs particle is supposed to impart mass to matter.
Scientists first measure the mass of the substance. They also know beforehand (from previous experiments) the exact mass of individual particles (molecule or atom) and hence can count the number of particles in the given substance by dividing the total mass of the substance taken by mass of individual particle.
blablablablablablablablaaaaaaaaaaaaaaaaaaaaa!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
You can divide the mass of a sample, by the mass of an individual particle.

The most mass of an atom is found in the nucleus.
If you mean the nucleus of an atom, different atom have different masses - an uranium atom has more than 200 times the mass of a hydrogen-1 atom (and most of that mass is in the nucleus).
The number of neutrons in an atom can affect the atomic mass of an atom.
It is the part of the atom with the greatest mass
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.

It is an inaccurate model, because there is no way to measure the exact mass, path, and charge of an atom
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.
Mass. And good job on cheating on the worksheet by using the internet!! ROFL
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.
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.
is a measure unit of the chemical substance , and is equal to the mass of particles of 12 C atom
