atomic mass unit , AMU (abbreviation)

We first need the energy equivalent of one atomic mass unit:

The mass of the neutron is also about one atomic mass unit.

There is only one stable isotope of gold (197 atomic mass units)!

Each isotope does not weigh an integer number of atomic mass units.

Its molecular weight is 359.5 atomic mass unit.

The unified atomic mass unit and the dalton are different names for the same thing.

The atomic mass unit is convenient for expressing the masses of atoms and molecules.

Thus the molecular mass of each member differs by 14 atomic mass units.

Keep in mind that the neutron that it came from also only weighs one atomic mass unit.

Atomic mass unit, used to express atomic and molecular masses.

The mass of a carbon atom was divided into 12 parts, and each part is known as atomic mass unit.

The standard atomic mass of nitrogen is 14.0067 atomic mass units.

Many antibacterial compounds are relatively small molecules with a molecular weight of less than 2000 atomic mass units.

You want a gram per mole and an atomic mass unit (amu) to be the same.

The "unified atomic mass unit" u was defined as:

Atomic weight: the mass of an atom, expressed in atomic mass units.

Atomic physicists deal with the tiny masses of individual atoms and measure them in atomic mass units.

We'd like to say that its mass is exactly 12 "somethings", and we call that something the atomic mass unit.

It has accelerated uranium ions to 345 MeV per atomic mass unit.

Avogardo's number of atomic mass units has a mass of one gram.

That number (Avogadro's number) is basically the conversion factor between atomic mass units and grams.

The C standard makes it useful to think about nuclear mass in atomic mass units for the definition of the mass excess.

These are significant in helium because of its low atomic mass of about four atomic mass units.

Mature renin contains 340 amino acids and has a mass of 37 atomic mass unit.

The mass number gives an estimate of the isotopic mass measured in atomic mass units (u).
