the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.

Atomic Mass Units.atomic mass unit
What is Carbon-12 atomic mass?
12. The number 12 refers to the atomic mass. More precisely, to the sum of neutrons + protons; but this is usually close to the atomic mass. In the case of carbon-12, it is exact, by definition.
What is the atomic mass-?
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
What is the atomic mass of colbat?
Cobalt is an atomic mass of 58.93 atomic mass units
The equation of atomic mass?
== The equation of atomic mass is protons+nuetrons== atomic mass. ===
What is one twelfth of the mass of the carbon 12 atom?
the answer is the atomic mass unit

What is the AMU of carbon?
The atomic mass unit (AMU) of carbon is approximately 12.01 AMU.
What describes the definition for the atomic mass of an element?
the atomic mass is the mass of an atomin the table of elements each element has its own specific box. the atomic mass is listed under the elemnts symbolEX. 2HE4.00
How many atomic mass units are there in carbon-12?
12 by definition.
What is Carbon-12 atomic mass?
12. The number 12 refers to the atomic mass. More precisely, to the sum of neutrons + protons; but this is usually close to the atomic mass. In the case of carbon-12, it is exact, by definition.
What is the definition of hyphen notation?
Element - Atomic Mass # Example: Carbon - 12
How many moles are in 5.87 g Ni?
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass. So if you have just 1 mole, the number of grams will be the atomic mass. Nitrogen's atomic mass is 14.007 grams.
How come the relative atomic mass can be a fraction?
The relative atomic mass is the mean mass of the isotopes of an element. Since, by definition, these have different numbers of neutrons, their masses are different. This results in fractional values.
How many gram does one mole of helium gas weighs?
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass (divide by one mole for units to cancel). So if you have just 1 mole, the number of grams will be the atomic mass. Helium's atomic mass is 4.003 grams.
What is atomic mass unit and how is it derived?
1 atomic mass unit is equivalent to the 1/12 the mass of a carbon-12 atom at rest. This is not considered an si unit because it is defined by a definition and not experimentally
Which best describes the definition for the atomic mass of an element?
The atomic mass of an element is the average mass of an element's isotopes, weighted by their natural abundance. It is expressed in atomic mass units (u) and is often close to the mass number of the most abundant isotope of the element.
